Please enter your email:

Torsional shear strain varies linearly across a homogeneous cross section.

 
 

Torsional shear strain is a maximum at the outermost radius for a homogeneous and a nonhomogeneous cross section.

 
 

Torsional shear stress is a maximum at the outermost radius for a homogeneous and a nonhomogeneous cross section.

 
 

The formula image can be used to find the shear stress on a cross section of a tapered shaft.

 
 

The formula image can be used to find the relative rotation of a segment of a tapered shaft.

 
 

The formula image can be used to find the shear stress on a cross section of a shaft subjected to distributed torques.

 
 

The formula image can be used to find the relative rotation of a segment of a shaft subjected to distributed torques.

 
 

The equation image cannot be used for nonlinear materials.

 
 

The equation image can be used for a nonhomogeneous cross section.

 
 

Internal torques jump by the value of the concentrated external torque at a section.
