A bar with cross sectional area A is subjected to equal and opposite tensile forces F at its ends. Consider a plan through the bar making an angle ? with a plane at right angles to the bar.
a.) What is the tensile (normal) stress at this plane in terms of F, A, and ? ?
b.) What is the shear (tangential) stress at the plane in terms of F, A, and ? ?
c.) For what value of ? is the shear stress a maximum?© BrainMass Inc. brainmass.com October 9, 2019, 3:42 pm ad1c9bdddf
