Problem 256 A vertical shaft AB is 5 ft long and bolted to a rigid support at its lower end A. At its upper end B is attached a horizontal bar BC which is 2 ft long. At the end of C is applied a force P = 180 lb. Force P is perpendicular to the plane containing points A, B, and C. Determine the twisting effect of P on the shaft AB and the bending effect at point A.

Solution 256

$T = 360 \, \text{ lb}\cdot\text{ft}$ answer

Bending effect $M = 5P = 5(180)$

$M = 900 \, \text{ lb}\cdot\text{ft}$ answer
