Clamps like the one shown are commonly used in
woodworking applications. This clamp has the dimensions
given in the table below the figure, and its jaws are
mm thick (in the direction perpendicular to the plane of the
picture).
a.) The screws of the clamp are adjusted so that there is a
uniform pressure of P = 150 kPa being applied to the
workpieces by the jaws. Determine the force carried in each
screw. Hint: the uniform pressure can be modeled in 2-D as a
uniform distributed load with intensity w = Pt (units of
N/m) acting over the length of contact between the jaw and
the workpiece.
b.) Determine the minimum vertical force (parallel to the
jaws) required to pull either one of the workpieces out of the
clamp jaws. Use a coefficient of static friction between all
contacting surfaces of μs = 0.56 and the same clamping
pressure given for part (a).

A short brass cyclinder (denisty=8530 kg/m^3, cp=0.389 kJ/kgK, k=110 W/mK, and alpha=3.39*10^-5 m^2/s) of diameter 4 cm and height 20 cm is initially at uniform temperature of 150 degrees C. The cylinder is now placed in atmospheric air at 20 degrees C, where heat transfer takes place by convection with a heat transfer coefficent of 40 W/m^2K. Calculate (a) the center temp of the cylinder, (b) the center temp of the top surface of the cylinder, and (c) the total heat transfer from the cylinder 15 min after the start of the cooling. Solve this problem using the analytical one term approximation method. (Answer: (a) 45.7C, (b)45.3C, (c)87.2 kJ)
