Homework Statement
A specimen tested in a simple torsion testing machine , the specimen was 12.5mm in diameter and the angles were read over a gauge length of 0.75m Determine the modulus of rigidity of the material taking the torque T as 4.5Nm and the angle of twist as 4.0 degrees
Homework Equations
T/J=τMax/R=Gθ\L
The Attempt at a Solution
J=∏(0.025)4/32
J=3.8349x10^-8
4.0degress=0.0698132
4.5/3.8349x10^-8=G(0.0698132)/0.75
=>G=126x10^7
Wondering if this looks correct ??
