Question
A rod specimen of ductile cast iron was tested in a torsion-testing machine. The rod diameter was 16 mm,
and the rod length was 360 mm. When the applied torque reached 254.8 N-m, a shear strain of 1780
microradians was measured in the specimen. What was the angle of twist in the specimen?
Part 1
Calculate the shear stress in the specimen.
Correct
Answer:
T= 316.97
eTextbook and Media
Part 2
Use Hooke's Law to calculate the shear modulus of the specimen.
answer:
G= i
MPa
