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.
