What is a Material in engineering

At a certain elevation, the pilot of a balloon has a mass of 120 lb and a weight of 119 lbf. What is the local acceleration of gravity, in ft/s2, at that elevation? If the balloon drifts to another elevation where g = 32.

So what is a wole numbe

What is stress corrosion cracking?

The stress is in the part working with static load. A. Dynamic stress B. Static stress or dynamic stre C. Static stress

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.

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
