A solid circular bar of diameter d = 50 mm (see figure) is twisted in a testing machine until the applied torque reaches the value T = 500 N - m . At this value of torque, a strain gage oriented at 45° to the axis of the bar gives a reading ɛ = 342 × 10–6.

Question
A solid circular bar of diameter d = 50 mm (see figure) is twisted in a testing
machine until the applied torque reaches the value T = 500 N · m . At this value
of torque, a strain gage oriented at 45° to the axis of the bar gives a reading
e = 342 x 10-6.
What is the shear modulus G of the material?
Strain gage
Įd = 50 mm
T= 500 N-m
T
Round to one decimal place.
G =
GPa
