C Dynamic Analysis and Aeroelasticity SECTION B Answer TWO questions from this section ENG2012-N The moment of inertia of a helicopter's rotor is 320kg. m². The rotor starts from rest and at t = 0, the pilot begins by advancing the throttle so that the torque exerted on the rotor by the engine (in N.m) is modelled by as a function of time (in seconds) by T = 250t. a) How long does it take the rotor to turn ten revolutions? b) What is the rotor's angular velocity (in RPM) when it has turned ten revolutions?

1. The development of thermodynamics since the 17th century, which was pioneered by the invention of the steam engine in England, and was followed by thermodynamic scientists such as Willian Rankine, Rudolph Clausius, and Lord Kelvin in the 19th century. explain what the findings or theories of the 3 inventors are!

Tires are one of the most frequently encountered applications of the gas laws that we never think about. We fill our tires with air, or with nitrogen, but it always works out the same way. Enough gas goes in, the tire inflates, and then the pressure starts going up. In this assignment, we’ll be investigating the ways that the gas laws impact how we treat our tires. Q1. I have good information that in Fast 29, Dominic Toretto (Vin Diesel) will need to refill a tire quickly during a dramatic moment. For this reason, he has a 3.00 L tank of compressed air that is under 2.7892*103 mmHg and is kept cool in dry ice at -35.0 °C. When Dom hooks his compressed air up to his completely empty 10.50 L tire at 39.2 °C and lets it run, what will his final tire pressure be, in atm? Assume all the air is transferred into the tire. Is his tire pressure above the 2.31 atm that he needs to save the planet/his family/his crew? Q2. Your car tire pressure sensor looks to see when your tire pressure…

ECO 5. AUTOMOTIVE. The power an engine produces is called horsepower. In mathematical terms, one horsepower is the power needed to move 550 pounds one foot in one second, or the power needed to move 33,000 pounds one foot in one minute. Power, in physics, is defined simply as the rate of doing work. The formula below gives the horsepower at 5,252 radians per second. https://philkotse.com/toyota-corona-ior-sale-in-baguio/1991-for-sale-in-aid7017151 625T 1313 where H is the horsepower and T is the torque a. Find the inverse of the model. b. If a taxi produces a horsepower of 200, what is the torque it generates? Solve here:

account_circle   Science PhysicsQ&A LibraryA child’s toy consists of a m = 31 g monkey suspended from a spring of negligible mass and spring constant k. When the toy monkey is first hung on the spring and the system reaches equilibrium, the spring has stretched a distance of x = 17.6 cm, as shown in the diagram. This toy is so adorable you pull the monkey down an additional d = 7.6 cm from equilibrium and release it from rest, and smile with delight as it bounces playfully up and down.  1. Calculate the speed of the monkey, ve, in meters per second, as it passes through equilibrium.  2. Derive an expression for the total mechanical energy of the system as the monkey reaches the top of the motion, Etop, in terms of m, x, d, k, the maximum height above the bottom of the motion, hmax, and the variables available in the palette.   3. Calculate the maximum displacement, h, in centimeters, above the equilibrium position, that the monkey reaches. A child’s toy consists of a…

Newton’s 2nd Law Lab (Modeling­ friendly lab)   Go to the PhET simulation Forces & Motion. https://phet.colorado.edu/sims/html/forces­and­motion­basics/latest/forces­and­motion­basics_en.html Select “Acceleration” Click to show Forces, Sum of Forces, Values, Mass, and Acceleration. There are two experiments for this activity – make sure you include both.   Experiment #1: Acceleration vs. Force In this lab you will determine the relationship between acceleration and net force. Choose a mass at the beginning, and keep it constant for this entire experiment. Set the friction to zero.  This will make your Applied Force equal to the net force. Record data for five different values of Applied Force. Graph Acceleration vs. Net Force. Graph this in Google sheets(you want a line graph - it should only have one line). Make sure that Applied Force information is used as the x value Make sure that Acceleration information is used as the y value Add a trendline – see what fits best –…

An electric motor's torque is a function of the speed at which it rotates. Many brushed AC motors have a linear toque curve as shown below. If the power output of the motor is equal to the torque (T) multiplied by the rotational speed in rad/s (w), what is the maximum power you can get out of the motor if the stall torque (Tstall) is 0.001 Nm and the no load speed (wno load) of 14,332 RPM? Give your answer in Watts. There are two ways to solve this: Use a stall torque and no load speed and plot the torque profile below and then plot the power versus rotational speed to find the maximum. The second method is to determine the mathematical relationship for power given the information at the start of the question and set the differential of power with respect to RPM equal to zero, and solve for the RPM to get the maximum. Tstall Wno load W

The left side of this equation tells how much energy Q the cylinder gives to the water while it cools. The right side of this equation tells how much energy Q the water and aluminum cup absorb from the cylinder to warm up. Because it is the same energy, they are equal. What is known in this equation? Mcyl 411.7 g, malum 46.5 g, malum+water = 175 g Can you find: mwater =? g Twater = Talum = 20°C (water and cup of room temperature) 90°C, T; = 35°C (hot cylinder and cool "cylinder+cup+water" temperatures) Tcyl kCal Calum = 0.22, Cwater 1 (specific heat of water and aluminum, measured in units kg-°C What are we looking for is Ccul - How we find it? Plug all the numbers into the equation (1), Ccul will be one unknown which you can calculate from the equation. Important, convert all the masses from grams to kilograms! After you find Ccyl, compare it to known value for the copper 0.093(our cylinder is made out of copper). |Ceyl -0.093| % : · 100% 0.093
