In advanced case studies, how is the safety of a torsion shaft verified?

By comparing the calculated shear stress to the material's yield strength

By ensuring the diameter is adequate

By calculating the maximum torque

By checking the length of the shaft

How does the polar moment of inertia (J) of a shaft affect its response to torsion?

A larger J reduces the shear stress and angle of twist for a given torque.

A larger J increases the shear stress and angle of twist for a given torque.

J does not influence the shaft's response to torsion.

A larger J only affects the angle of twist, not the shear stress.
