1. Homework Statement
Compute angle of twist of one end relative to other if a torque of 850 lb-in is applied uniformly along the length. Shaft has two flats (not just the 1 pictured!) 1.25 " is measurement across flats.
Homework Equations
J = C r^4
The Attempt at a Solution
I had to hand in the page with the question on it recently :(
so, here are the governing equations, need some direction on how to tackle it:
so the value of J is easily computed (table: 0.625" / 0.875" = C of around 0.93 x 0.316 = 0.294)
angle = [(torque)(length)]/[GJ])
so since there are two J values, how is this handled? thanks
