A shaft of 0.3 metres long and 45mm diameter twists 2 degrees under a torque of 7kNm.
On a tensile test the same material extends 0.015mm on a length of 110mm. If the tensile force producing this extension was 500N and the diameter of the test piece was 5mm determine the values of :
G, E, v, K
Any help/ guidance would be greatly appreciated
