1. Torsional stress may be defined as that shear stress which acts on a transverse cross-section that is caused by the action of a twist.
2. Normal stress and normal strain (which are caused by tension and compression of a member) occur when a force is applied perpendicular to an area.
3. Torque on a shaft is the main cause of shear stress.
4. The torsion induced when torque is applied to a shaft causes a distribution of stress over the shaft's cross-sectional area.
5. Mathematically, Torsional stress , Where =Torque applied, radius of cross-section, polar moment of inertia.
6. For example, consider a traffic sign mounted on a single rod on a windy day.
7. The wind twists the sign, causing shear stress to be exerted along the cross-section of the structural member.
Therefore, Torsional stress is the shear stress that acts on a transverse cross-section which is caused by the action of a twist.

A science student is riding on a flat car roof train that is traveling at a constant speed of 10 mph on a straight horizontal track. The student throws a ball into the air along a path that he just made to make an initial angle of 60 degrees with the horizontal and to be in line with the track that the student's professor, who is standing nearby, observes the ball rising. How high does the ball rise vertically?
