Reading Question 8.03

What is the internal torque over the a-a section? 00 lb (a 10 in 12 in O 1000 lb-in. 600lb-in O 720 lb-in O 960 lb-in. O 1200 lb-in O 800 lb.in

Solution

SOLUTION:

Vertical Force causing Torque = 100 x (4/5) = 80 lb

Torque T = 60 X 12 = 960 lb-in

NOTE: Horizontal component of force will cause only bending in shaft.
