engineering recuitment GATE ME 2023-24 Test Series Strength of Materials Shear Force and Bending Moment Shear Force
A simply supported beam supports a point load P as shown. The cross – section of the beam is rectangular in shape of area A. The maximum shear stress (τmax) and average shear stress (τavg) induced in the beam is:
1
\({\tau _{avg}} = \;\frac{{2P}}{{3A}}\)
2
\({\tau _{avg}} = \;\frac{P}{A}\)
3
\({\tau _{max}} = \;\frac{P}{A}\)
4
\({\tau _{max}} = \;\frac{{3P}}{{2A}}\)
