10. an engineer is designing a total hip implant. she intends to make the femoral stem out of titanium because it forms a good interface with bone. however, since titanium does not have optimal wear properties she intends to make the ball component out of stainless steel and attach it using a press fit. should she be worried about corrosion? if so what types of corrosion could take place?

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature

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

What is a monomer? how do they form a ploymer from the view point of chemical bonding?
