Avibrating system with friction damping has xo=0.05m, x=0.004m, fn=2hz (a) determine the friction coefficient (b) determine the number of half cycles for the system come to complete stop (c) determine the decay for each cycle

Apiston-cylinder with a volume of 0.25 m3 holds 1 kg of air (r 0.287 k/kgk) at a temperature of 100 c. heat transfer to the cylinder causes an isothermal expansion of the piston until the volume triples. how much heat is added to the piston-cylinder?

Burgers vector is generally parallel to the dislocation line. a)-true b)-false

Vibration monitoring this technique uses the noise or vibration created by mechanical equipment and in seme cases by plant systems to detemine their actual condtion. a)- true b)- false
