TITLE- SHEAR STRENGTH EXECUTIVE SUMMARY
The purpose of this lab was to find the shear strength of three materials i. e. Steel ,Brass and Aluminum. The values of the shear strength from the table indicate that the steel has maximum shear strength whereas aluminum has least shear strength. OBJECTIVE

The objective was to know how important is the shear strength while making designs by testing shear strength of three materials. THEORY
According to H.W. Morrow and Robert P. Kokernak, Statics and Strength of Materials, eighth Edition:

Shear stress is a type of stress which is caused by two forces acting parallel to the cross sectional area and these forces are acting in opposite directions.

Shear strength is the maximum force divided by cross sectional area, where the forces are parallel to the area and both are in opposite direction.

The relation between shear strength and tensile strength is that shear strength is about three-fourths of tensile strength.
