To test orthopedic materials, two rods of the same dimensions are subjected to identical compressive forces on their ends. One rod is made of stainless steel (Y = 180 X 109 Pa), the other is made of titanium alloy (Y = 110 X 109 Pa). Which rod undergoes the greatest change in length?

A. Stainless steel rod
B. Titanium alloy rod
C. Same for both

The rocket is fired vertically and tracked by the radar station shown. when θ reaches 66°, other corresponding measurements give the values r = 32700 ft, r¨ = 85 ft/sec2, and θ˙ = 0.019 rad/sec. calculate the magnitudes of the velocity and acceleration of the rocket at this position.

Consider the growth of a 20-nm-diameter silicon nanowire onto a silicon wafer. the temperature of the wafer surface is maintained at 2400 k. assume the thermal conductivity of the silicon nanowire is 20 wm-1k-1 and all its surfaces including the tip are subjected to convection heat transfer with the coefficient h = 1×105 wm-2k-1 and t∞ = 8000 k. when the nanowire grows to l = 300 nm, what is the temperature of the nanowire tip (t (x =
