= 900 kN- PROBLEM 1. Two forces P = 5 kN and F = 8 kN are applied at the top of the 100-mm-diameter steel post shown. Also, a torque T mm is applied to the post. L is the distance from the top of the post to points K and H. L = 300 mm. 1. Determine the actual state of stresses point H (3 points). Perform free body diagrams of the post (0.5 points). Draw the plane stress element at point H (0.5 points). 2. Draw the Mohr Circle to determine the following (all calculations must be shown): i. Principal stresses (2 points) ii. Maximum shear in plane stress (1 point) iii. Principal stress angle (0p) - show at Mohr circle (0.5 point) iv. Maxmimum in plane stress angle (0s) - show at Mohr circle (0.5 point) 3. Apply the maximum distortion energy theory to determine is the material fails. Use o 250 MPa. (2 points)
