A belt sander, shown in Figure P1.63, weighs 10 lb and has a belt speed of 1000 ft/min. A downward force of 10 lb (in addition to the weight) is applied on the sander. If the coefficient of friction between the belt and a flat table top being sanded is 0.30, determine
(a) the power transmitted by the belt in hp, and
(b) the work done while sanding the table top for 15 minutes in ft-lb.
List three different factors responsible for the increase in pressure resulting from the transfer of heat to the tank. List ways in which this accident could have been avoided.

Use these results to estimate the area of silicon solar cells required to satisfy the community power requirements. Write a short narrative discussing your assumptions and analysis.
Assume that heat is transferred from the metal to the mould via radiation and conduction. Then heat is conducted through the mould and convected to the atmosphere. Stating all assumptions, derive a system of equations to carry out a transient anal..
Calculate the intensity of sound for each speaker expressed in W/m2 and comment on the results.
An applied force of 26.5 MN is distributed uniformly over a 152-cm2 area; however, it acts at an angle of 42° with respect to a normal vector (see Fig. P1.33). If it produces a compressive stress, calculate the resulting pressure
