April 24 Daily Question: Solve for Twist on a Shaft
NCEES Civil PE Specification IV.C.: Bending
Shaft ABCDE is subjected to clockwise torques 590 lb-ft, 880 lb-ft and 750 lb-ft at points B, C and D respectively.
Supports A and E are both unyielding.
The diameter of the shaft varies as shown in the figure.
Given modulus of rigidity G = 11.5x106 psi, determine the reaction at support E.
