"7laha - Torsion 2"
Source: mind of Kites Ex:
Cylindrical Composite shaft (steel and brass)
Steel core (G=77Gpa) 50mm diameter and 5mm brass (39Gpa)
Jacket the shaft consist from two parts
Connected by bolts as shown
The right part (L =.5m) is fitted with torsion spring (K=3N.m/ rad) and the left part (L=.4 m) is fitted with fixed thin steel angle (.127*.127*.0095 m) length =.3 m
If a worker made a force=70N by a tool (L=.2m) on the left sec of the square box of bolts, the bolts permit a2 deg rotation of one flange with respect to the other before the flanges start to rotate as single part. Note that the relative rotation angle does not depend on if the ends of parts are fixed or not.

Determine :
1-The max shear stress on the steel core and the brass jacket in the right part.
2-The corresponding angle of twist in the steel angle
