sir could u pls explain how to solve this sum A bar of cross section A is subjected to equal and opposite tensile force F at its ends If there is a plane through the bar making an angle Q with the plane at right angles to the bar in the figure F F a Find the tensile stress at this plane in terms of F A and Q b What is the shearing stress at the plane in terms of F and Q c For what value of Q is tensile stress a maximum
