    2021-7-26 · We learned about torque and torsion in this lesson. This different type of loading creates an uneven stress distribution over the cross section of the rod – ranging from zero at the center to its largest value at the edge. From this analysis we can develop relations between the angle of twist at any a point along the rod and the shear strain within the entire rod.
