Layout of controls familiar
1 2 3 4 5 N/A
The layout of the controls could be difficult to remember when not looking at the lever. Accelerating and decelerating can be easier to remember considering the lever must be pushed up to accelerate and pushed down to decelerate, however to “cancel” the cruise control or to turn cruise control on or off may cause the driver to have to read the lever while driving, Function Keys Limited
1 2 3 4 5 N/A
There are 4 functions on the lever. You can push forward to cancel the cruise control, up to increase the speed of your cruise control, down to “set” your cruise control, also pressing down you can resume your last saved speeds and lastly, there is a small button on the very end to turn the cruise control on and off. Touchscreens
1 2 3 4 5 N/A
There is not a touch screen component on this model of
Camry. Is unintentional operation avoided
1 2 3 4 5 N/A
The cruise control lever is located directly behind the lower right-hand side of the steering wheel. It is very possible to unintentionally turn the cruise control on, or off as well as possibly accelerating/decelerating or setting it due to the location of the lever. Also, the 2
actual movements of the lever are on a very small scale.
You could easily push the lever in the wrong direction accidently, resulting in the wrong intented action. Label and Symbols Used
1 2 3 4 5 N/A
The labels and the symbols on the small cruise control lever seem crowed. There are 4 arrows (which point in all directions) one + and one – symbol, the actual cruise
control symbol, on/off, RES, CANCEL, and SET written on the very small lever. Use of color limited
1 2 3 4 5 N/A
The lever is black with white writing. No other colors are present on the lever. Movement and objective of controls consistent with operation
1 2 3 4 5 N/A
Considering how close the lever is located to the driver’s right hand and how compact the lever is, it seems the driver can easily choose the setting and speed of the cruise control without having to reach. Also, depending on how big the driver’s hands are, they
could possibly keep their hand on the wheel while still operating the cruise control setting. The only drawback
is: if the driver is not familiar with the different setting and how to select the option they want, they may have to take their eyes off the road to read the lever. Hands free operation available
1 2 3 4 5 N/A
The cruise control on this model cannot be used “hands
free”. To accelerate, set, decelerate, or turn on and off musts be done by the user manually. Total

Dialogue suitable for task skill
1 2 3 4 5 N/A
The task of turning on cruise control, and being able to
accel, decel and set the control seem simple. It may be
even more simplified if there were individual buttons
for each option of cruise control rather than all options
located on one tiny lever. Dialogue clear on next action
1 2 3 4 5 N/A
When I first started driving my 2011 Toyota Camry,
without reading the manual, it took me some time to
figure out which tap of the lever enacted the action of
the cruise control. It is all on the user to know how the
cruise control lever operates. Dialogue Consistent
1 2 3 4 5 N/A
The dialogue is consistent when it comes to “user
friendliness”. For every direction the lever is push, the
vehicle consistently performs the actions asked of it. Dialogue Forgiving
1 2 3 4 5 N/A
First, the lever is small compared to the other
components of the vehicle. Second, to push the lever
up, down, and forward can be a little tricky. The
movements of the lever are very minimal, so it could be
easy to accidently push the lever in the wrong direction
resulting in the wrong action enacted. Dialogue suitable for It is fairly simple to learn how to operate the cruise
control and use it for your advantage while driving

Layout of controls familiar
1 2 3 4 5 N/A
The layout of the controls are very familiar considering they are arranged in a circle just like a compass (north, south, east, west) This layout is something that is used in many other technological systems such as game controllers, thermostats, ect making it easy to identify/operate without having to refer to the user manual. It is also located on the right side of the steering wheel resulting in being able to keep both hands on the wheel. Function Keys Limited
1 2 3 4 5 N/A
There are no mistaking the buttons. Each button has its own function and cannot be used for any other purposes other than its intented function. Touchscreens
1 2 3 4 5 N/A
There is no touchscreen associated with the cruise control. 5
Is unintentional operation avoided
1 2 3 4 5 N/A
Previously stated, each individual button has its own purpose. The buttons are spread out enough to where unintentional operation is very unlikely. The only way you may press the wrong button is if you press in between the buttons (diagonally). Label and Symbols Used
1 2 3 4 5 N/A
There are 4 symbols that are on the cruise control panel. Those are: +RES, -SET, CANCEL, and the cruise control symbol to turn on/ off the cruise control function. The labels are spaced far enough apart, so they are distinct with no way of mixing them up cognitively(we do have “brain farts” occasionally). Use of color limited
1 2 3 4 5 N/A
Use of color is user friendly. The cruise control panel is black with white writing. Movement and objective of controls consistent with operation
1 2 3 4 5 N/A
The way the cruise control panel is set up, it is directly
on the steering wheel, the right hand side to be exact. There is very minimal movement being performed on the driver’s end when enacting the different functions of the cruise control making it safer, in my opinion. Hands free operation available
1 2 3 4 5 N/A
There is no handsfree option available regarding cruise control with the 2018 Toyota Camry LE. Total

Dialogue suitable for task skill
1 2 3 4 5 N/A
The way the cruise control panel is located on the
steering wheel, as well as being simply labeled makes
the function easy to perform when it relates to the task
of operating the cruise control. Dialogue clear on next action
1 2 3 4 5 N/A
With the simplified cruise control panel located on the
steering wheel, it is fairly easy to know the next action
you want to perform using the cruise control .
Dialogue Consistent
1 2 3 4 5 N/A
When you press a particular function of the cruise
control, it is an extremely consistent dialogue. If you
enact the acceleration button, the car will accelerate,
ect. Dialogue Forgiving
1 2 3 4 5 N/A
Each button has its own function. So, if you accidentally
press the wrong button, it will not correct you and
perform the function you have originally asked it to
perform. In turn, you will have to correct the issue
yourself by selecting the correct function/button. Dialogue suitable for individualization/learning
1 2 3 4 5 N/A
The cruise control allows for driver individualization
easily. You can select how fast/ slow you want to
consistently go with just the touch of a few buttons. You
can also “save” your last speed to resume whenever
you want to re-enable your cruise control. Total

Summary between vehicle #1 and vehicle #2
I chose to use my vehicle, the 2011 Toyota Camry base model as my choice for vehicle #1. The vehicle I used to compare to vehicle #1 was my mother’s 2018 Toyota Camry LE. With some convincing, my mother let me drive her vehicle around for a few days so I could get a true comparison. I chose to compare the vehicle’s cruise control option. There was a clear winner. When evaluating both vehicles, vehicle #1 had a total of 38 points while vehicle #2 had a total of 59 points. After doing some research, the Toyota Camry changed its cruise control design in 2018 which resulted for the cruise control function to be located directly on the right side of the steering wheel rather than under the right side of the steering wheel. I have always had difficulties when using my cruise control (vehicle #1) because the lever that contained the cruise control functions was extremely small, and overcrowded with signs and symbols. Nine times out of ten I would have to take one hand off the steering wheel to operate my cruise control. Not only that, the cruise control was not operated by pushing buttons, but by moving the lever slightly up/down/forward and a small button on the end to turn it the function on and off. Because of the location of the cruise control lever, I would accidently enact the feature because my knee or hand would bump it unintentionally. While driving the 2018 model, I never unintentionally turned on the cruise control due to the new location (directly on right side of steering wheel). Not to mention, I never had to take
my hand off the steering wheel to turn on the cruise control. I am starting to wonder
how many other older model Camry drivers have had the same issue as I when it comes to the location of the cruise control function. In my opinion, the updated location of the cruise control is a major win for Camry drivers. Now that we have touched on location, let’s move to the functionality of the control. The 2011 Camry cruise control is operated by a lever. You can tap the lever down, up, forward, and there is a little button on the end of the lever to turn the control on and off. The movement of the lever was so small, it could easily be touched in the wrong direction giving an unwanted outcome. The 2018 Camry has a compass like panel with buttons that are much easier to intentionally press. Overall, the 2018 Toyota Camry LE’s cruise control is much easier to operate, safer (can keep both hands on the wheel when using cruise control) as well as being more user-friendly with symbols that are easier to decipher. I noticed while driving my mother’s car, I was more prone to individualize my cruise control to make it work for me. The longer I have driven my 2011 Camry, the less I have opted in to use
the cruise control feature due to the location, functionality and user friendliness. 7

QUESTION 2
A company needs to choose one supplier for a particular type of silicon wafer used'in the production of
semiconductors. The company has three options. Supplier A sells the silicon wafers for $2.50 per wafer,
independently of the number of wafers ordered. Supplier B sells the wafers for $2.40 each but does not
consider an order for less than 2,000 wafers. Supplier C sells the wafers for $2.30 each but does not accept
an order for less than 3,000 wafers. Assume an order setup cost of $100 and an annual requirement of 20,000
wafers. Assume a 20% annual interest rate for holding cost calculations.
a. Which supplier should be chosen to minimize the total annual cost for the wafers, and what is the
optimal order quantity?
b. If the replenishment lead time for wafers…

Steam at T1 = 320 °C flows in a cast iron pipe (k= 80 W/m. °C) whose inner and outer diameters are
5 cm = 0.05 m and D₂ = 5.5 cm = 0.055 m, respectively. The pipe is covered with 3-cm-thick glass wool
insulation with k = 0.05 W/m. °C. Heat is lost to surroundings at T2 = 5 °C by natural convection and
radiation, with a combined heat transfer coefficient of h₂ = 18 W/m². °C. Taking the heat transfer coefficient
inside the pipe to be h₁ = 60 W/m². °C, determine the temperature drops across the pipe and the insulation.
The determination is based on a unit length of the pipe (L = 1 m).
Assumptions
1. Heat transfer is one-dimensional since there is no indication of any change with time.
2.
Heat transfer is one-dimensional since there is thermal symmetry about the centreline and no
variation in the axial direction.
3. Thermal conductivities are constant.
