A 3.7 g mass is released from rest at C which has a height of 1.1 m above the base of a loop-the-loop and a radius of 0.2 m. The acceleration of gravity is 9.8 m/s 2. 1.1 m 0.2 m B D C A 3.

Define the stress and strength? A material has yield strength 100 kpsi. A cantilever beam has length 10 in and a load of 100 Lbf is applied at the free end. The beam cross section is rectangular 2""x5'.

2. Suppose you yell in a canyon. You hear the echo of your voice 0.8 seconds later with an amplitude 5% as loud. But, that will echo back again from your side, so you will hear another echo 0.

Composite materials such as GFRP have low strength to weight ratio. a) - True b) - False

What is the weight of a glider with a mass of 5.3 grams? (Hint: watch your units!)

16 Suppose that a steel of eutectoid composition is cooled to 550°C (1020°F) from 760°C (1400°F) in less than 0.5 s and held at this temperature.

The rotor in a shaded pole motor consists of A coils energized by alternating current B a short circuited loop of copper wire c a permanent magnet D an iron cylinder

What factors are likely to promote the formation of stress corrosion cracks?

Find the mass if the force is 18 N and the acceleration is 2 m/s2
