Fill in the blanks:
Q1.
The rigid bar ABCD of negligible weight is initially horizontal, and the steel
rods attached at A and C are stress-free. The 20-kip load is then applied and the
temperature of the steel rods is changed by AT. Find AT for which the stresses in the
two steel rods will be equal. Use a = 6.5 x 10-6F and E = 29 x 10° psi for steel.

Fill in the blanks:
Q3. Determine the inner and outer
diameter of the hollow shaft which
will replace a 76 mm solid shaft
made of the same material. The
hollow shaft should be as strong in
torsion but it weighs only half as
much as the solid.
