Problem X4-2, MECH 3035, Spring 2019
Vertical force P= 250 Ib acts on end B of the L-shaped solid round bar as shown in the figure. The front view lies in the x-y plane as shown, and the top view lies in the x-z plane. The diameter of the bar is 2.00 in. Point A is on the top of the bar.
a) Find the bending moment and torsion acting on the bar at the cross section where point A is located. Use the given coordinate system to describe these moments.
b) Find the bending stress σxx acting on bar at point A, including its sign.
c) Find the shear stress due to torsion acting on the bar at point A. Is this shear stress a value of rxy or a value of rxz? Include the sign as part of your answer.
