7.
What is meant by sprung mass and unsprung mass?
Unsprung mass incorporates the mass of parts, for example, the wheel axles, wheel direction, wheel center points,
tires, and a segment of the heaviness of driveshafts, springs, safeguards, and suspension joins.
8.
Why should unsprung mass be as low as possible?
In a vehicle with a suspension, for example, a car, cruiser or a tank, sprung mass (or sprung weight) is the segment
of the vehicle's complete mass that is upheld over the suspension, remembering for most applications around half of the heaviness of the suspension itself.
9.
Explain ride height?
Decreasing unsprung weight is the way to improving dealing with. The lower the unsprung weight, the less work the
stuns and springs need to do to keep the tires in contact with the street over rough surfaces.

Explain the spring characteristics of the linear and variable rate spring.
Linear rate spring:
The most presentation arranged and springs intended for hustling will have a direct rate. The reliable idea of direct rate springs makes the vehicle stable, advances foothold, and makes the vehicle more unsurprising for the driver.
Variable rate spring:
Progressive springs become stiffer rapidly as they are compacted. Reformist springs consider a smooth ride over little knocks and have firm qualities when taking a piece hit, for example, a pot opening or a hard corner.
16.
Explain how the linear rate spring operates?
Direct springs have equivalent distance between each curl all through the whole length of the spring. With direct springs, the spring rate is consistent and isn't influenced by the heap following up on the spring. On the off chance that one applies a 100 lb burden to a spring with a pace of 100 lbs
17.
Explain the design and operation of the variable rate spring?

Complete the following statement about leaf spring suspension using the following words.
Words: Attaches, Bumps, Centre, Clips, Consist, Flexes, Leaf, Leaves, Monoleaf, Multiple, Noise, Passenger, Plastic, Problems, Ride, Springs, Stiffer, System, Vehicle’s
Although leaf __Springs________ were the first type of suspension spring used on automobiles, today they are generally found only on light-duty trucks, vans, and some __Passenger________ cars. There are three basic types of leaf springs: multiple leaf, _Monoleaf_________, and fibre composite. Multiple-Leaf Springs Multiple-leaf springs __Consist________ of a series of flat steel leaves that are bundled together and held with _Clips_________ or by a bolt placed slightly ahead of the __Centre________ of the bundle. One leaf, called the main leaf, runs the entire length of the spring. The next ____Leaf______ is a little shorter and attaches to the main leaf. The next leaf is shorter yet and __Attaches________ to the second leaf, and so on. This _System_________ allows almost any number of leaves to be used to support the _Vehicle’s_________ weight. It also gives a progressively _Stiffer_________ spring. The spring easily flexes over small distances for minor _Problem_________. The farther the spring is deflected, the stiffer it gets. The more __Flexes________ and the thicker and shorter the leaves, the stronger the spring. It must be remembered that as the spring __Bumps________, the ends of the leaves slide over one another. This sliding could be a source of ___noise_______ and can also produce friction. These __Problems________ are reduced by interleaves of zinc and __plastic________ placed between the spring’s leaves. As the _multiple_________ leaves slide, friction produces a harsh __ride________ as the spring flexes. This friction also dampens the spring motion.

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…

Question 2
You are a biomedical engineer working for a small orthopaedic firm that fabricates rectangular shaped fracture
fixation plates from titanium alloy (model = "Ti Fix-It") materials. A recent clinical report documents some problems with the plates
implanted into fractured limbs. Specifically, some plates have become permanently bent while patients are in rehab and doing partial
weight bearing activities.
Your boss asks you to review the technical report that was generated by the previous test engineer (whose job you now have!) and used to
verify the design. The brief report states the following... "Ti Fix-It plates were manufactured from Ti-6Al-4V (grade 5) and machined into
solid 150 mm long beams with a 4 mm thick and 15 mm wide cross section. Each Ti Fix-It plate was loaded in equilibrium in a 4-point bending
test (set-up configuration is provided in drawing below), with an applied load of 1000N. The maximum stress in this set-up was less than the
yield stress for the…

Case Study – The New Engineer
Jeff was just hired by GSI, Inc. to be their Environmental and Safety Coordinator. This is Jeff's first position after completing his engineering degree. He had taken a course in safety engineering as part of his studies and felt confident that he could handle the job.
Management at GSI, Inc. has assured him that they are committed to maintaining a safe workplace. They have never had an individual dedicated to this task full-time. They will implement his recommendations if he can justify them.
As Jeff begins to get familiar with the operations, he spends considerable time on the production floor. He notices workers clean their tools before break with a liquid from an unmarked 55-gallon drum. They also use this liquid to clean residue from their skin. They use paper towels to dry their tools and hands, throw these towels in the trash, and head to the break room for a snack and/or smoke.
