Assignment:
Question 1. A solid round steel shaft 3 1/2 inches in diameter transmits 100 HP at 200 RPM. Determine:
a. Torsional stress in the outer fibers
b. Angle of twist per foot of shaft
c. Increase in stress at the outer fibers if the shaft is made hollow with a 1 1/2 inch bore.
d. Stress at the inner fibers of the hollow shaft.
e. Angle of twist per foot of hollow shaft.
Question 2. For the beam shown, plot the shear and moment diagrams. Label each diagram with shear and moment values at the points of interest.
