Alift up system is used to transport objects among different floors. the two bearings on both ends of the shaft have the same dimension (l = 1 inch and diameter d = 2 inch), and they are made of steel-backed, ptfe coated bronze. the load bearing statistics are as follows: pmax = 36,000 psi; vmax = 390 ft/min; (pv)max = 51,000 lb-ft/in2-min. a cable is located at the midpoint of the shaft that is used to lift the chamber. the radius of the drum on the shaft is 6 inches. if the speed of the lifting chamber is 18 in/s, find the maximum load this lifting system can support.

1in2 processor chip can be modelled as an isothermal plane wall of silicon, isothermal on both sides. the power input to the bottom of the plane wall, or the processing power of the chip, often called the thermal design power (tdp), is 100w. assume the periphery is adiabatic. the silicon is 400 microns thick. the temperature at the junction, or in this case on the bottom of the isothermal plane wall, is 85°c. what is the top surface temperature, assuming that the only mode of heat transfer is conduction
