A bar of steel 1 by 1½ in cross section and 6 in long is subjected to a pull of 6000 lb. What is the average tensile stress in the bar?© BrainMass Inc. brainmass.com October 24, 2018, 5:34 pm ad1c9bdddf
Since the direction of the force is unspecified, I will assume that the pull is axial ...
The answer is given succinctly with simple equations.
Elasticity: Tensile stress - normal, tangential; shear stress
See attached diagram.
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?View Full Posting Details
