Lesson 12 Assignment 12 (2)

Tire manufacturers recommend that you check your tire pressure monthly to avoid unnecessary tire wear and enhance safety. This is best done when the tires are cold meaning; the car has not been driven for at least 2 hours. Since you leave for work before the sun comes up you decide to inflate your tires to the recommended pressure right after you get home from work in the afternoon when the tires are still warm. What would you find if you rechecked your tire pressure after the tires have cooled down? A.Tire pressure has decreased because there is a decrease in kinetic energy of themolecules resulting in more collisions with the inside walls of the tire thusincreasing the pressure inside the tire. B.Tire pressure has increased because there is a decrease in kinetic energy of the molecules resulting in fewer collisions with the inside walls of the tire thus decreasing the pressure inside the tire. C.Tire pressure has increased because there is an increase in kinetic energy of the…

C)If both cyclists have 170 mm cranks on their bikes, what will be the mechanical advantage (considering only the movement of the feet with a constant force for walking and riding), in percent, that each rider will have achieved over walking the same distance? (This can be found by dividing the distance wallked by the distance the feet move in riding.)

They lay 250 bricks each, but Josh finishes this task in three (3) hours while Jake requires 4.5 hours to complete his part. select the BEST response below: Jake does more work than Josh O Josh does more work than Jake Both Josh and Jake do the same amo O of work and have the same amount of power Both Josh and Jake does the same O amount of work, however, Josh has m power than Jake.

Truncation errors are increased as the round-off errors are decreased.Group of answer choices True False Say, you have a thermometer and you are checking the temperature of a body that has a temperature of 36o Using your thermometer five times, it gives you the following measurements: 29oC, 29.2oC, 29.3oC, 28.9oC, and 29.1oC. What can we conclude about the accuracy and the precision of the thermometer?Group of answer choices The thermometer is not accurate and not precise The thermometer is faulty. The thermometer is accurate and precise The thermometer is not accurate but precise.

You go on a road trip to escape the cold winter days of Kirkland Lake, Ontario to the warm beaches of Moonbeam, Ontario. Since it is a long drive and you are leaving early in the morning, you make sure to check the tire pressure and make sure it is at the recommended level. At lunchtime, you stop for gas and decide to check your car's tire pressure again. You also notice that the tires seem to be a little bit larger than when you left. The driver's manual suggests a pressure between 205 and 220 kPa. Knowing that the tires heat up while driving; do you expect your reading to be high, low or the same as the recommended tire pressure? Why? Since you plan on staying in Moonbeam a while to see the sights, you think it would be best to adjust your tire pressure. What adjustments should be made to your tires? Should you make these adjustments as soon as you arrive, or the following day?

How may acoustic designers alter the design of a room, which was previously used for music performances, into a room now to be used for spoken word performances? Use annotated diagrams for your response

You need to run some vibrations tests and your lab has an accelerometer (2nd order system) that has a natural frequency (resonance) at 3,000 Hz and damping ratio of 0.05. The vibrations you wish to measure are in the range of 100 - 1,200 Hz. a. What are the amplitude error (in %) and phase shift (in degrees) expected at the upper end of the vibration frequency range (1,200 Hz)? b. What is the maximum frequency that you can measure to have no more than 1% error in the amplitude of the reading? c. Is this a suitable choice of accelerometer for this measurement? Why or why not?

2) What is audiometric testing? What, if anything, does it have to do with hearing conservation programs? 3) A piece of machinery is placed in the corner of a manufacturing area (to get it as far away from as many people as possible). If the machinery is generating 96 dB of sound power, what sound pressure level would be experienced my someone standing 1 meter from the machine? (Assume no correction is necessary for atmospheric temperature or pressure).

What is the shape factor F12 for the situation shown in Fig. 1 below ?

Select atleast two testing devices from among the categories (you may go beyond two). Discuss its application and methods of use. a. testing for speed (Tachometer), b. Testing of Air Consumption (Air-box method/viscous-flow meter), c. testing of exhaust smoke (Bosch/Hartridge/PHS), d. testing of exhaust emission (flame ionization detector/spectroscopic analyzers/gas chromatography) e. testing of torque (absorption dynamometer/transmission dynamometer).

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…

Question 2 In a test measuring the life span of a certain brand of tire, 100 tires are tested. The results showed an average lifetime of 50,000 miles, with a standard deviation of 5,000 miles. One hundred thousand of these tires have been sold and are on the road. (a) After what mileage would you expect 10% of the tires to have worn out? (b) How many tires are expected to wear out between 60,000 and 70,000 miles? (c) How many tires are expected to have a life of less than 20,000 miles? (d) What are your major assumptions in the calculations for (a), (b) and (c)? (e) Estimate the 95% confidence interval on the population mean.

Two sport utility vehicles (SUVs) are being considered by a recent engineering graduate. Using the following data evaluate which sport utility vehicle is better. Use six attributes in your a point, overall appearance, comfort, safety, reliability, and fuel mileage. Larger scores on overall appearance, comfort, safety, reliability, and fuel mileage are preferred to smaller ones. Click the icon to view the table with data you have gathered about the SUVs. Determine attribute weights and use the nondimensional scaling technique to find the resulting set of vehicle scores. Fill in the table below. (Round to two decimal places.)
