1. A 1.5-m long circular cross-sectioned bar with r = 1 cm is under a combination of bending moment of 70 N-m and torque of 50 N-m. Determine (a) the location of the critical point on the bar. (b) the resulting normal stress at the critical point. 6 (c) the resulting shear stress at the critical point. T (d) the principal stresses, principal direction, and maximum shear stress at the critical point. 6,2› Op, (max (e) Draw a Mohr's circle representing the state of stress at the critical point.
