Question

1) For the loading of the beam shown below, determine the maximum normal and shear stress at the wall if Kt for bending is 2.7 and K, for torsion is 2.3 If we use a steel with an Sy 600 MPa, what is the "safety factor" if we only consider the maximum normal stress? Notice the bending moment, start with a cross product to determine the moment at the wall. The vector R-[0.25,0,0.3] in meters 200 mm 25-mm-dia. round rod bent into crank 250 mmR 100 mm 1000 N FIGURE P4.49 500 N The bending moment it 325 N-M, and the torque is 250 N-M
