# How to calculate shear stress at various points for an I-shaped cross-section

Shear stress refers to a stress that induces shear. It offers the similar dimension as pressure. Pressure produces compression whereas shear stress produces shear. Shearing stress occurs as the forces parallel to the area withstand the force. Shearing stress is also called as tangential stress.

This construction video tutorial shows the detailed calculation method for shear stress at different points toward an I-shaped cross-section. Besides, the video briefly demonstrate the process for drawing the shear stress for a beam that contains an I-shaped cross section.

By watching this construction video, one will be familiar with different types of shear stress formulas. The formulas are applied for providing cross-section.

The video is recorded on an i-beam with an internal shear force of 50 kilonewtons that is obtained from a shear diagram. Itâ€™s direction is upward on the cross section. The calculation is done for finding out shear stress of point A and point B.
