Torsional Shear Stress

[ForgottenMem]

I require some help please.

 

I know :

 

Rule: T/J = t/r = GΘ/L

 

L = length = 0.33

r = radius = 0.025

D = diameter = 0.5

 

 

The starting points and stages would help. I have to hand this in next wednesday, i thought i would ask the community.

Determine the distribution of shear and angular deflection due to torsion in a circular shafts.

 

1-Calculate the maximum shear stress produced in the shaft due to torsion.

2- Calculate the maximum shear strain

3-Calculate the angle of twist between the two pulleys.

 

F1 (N) 2500

F2(N) 2500

A (m) 0.1

B (m) 0.15

C (m) 0.08

D (m) 0.05

P (kw) 2

N (rev/min) 300

Thanks.
