uiz 1. 1) A solid steel shaft in a rolling mill transmits 20 kW of power at 2 Hz. Determine the smallest safe diameter of the shaft if the shear stress tw is not to exceed 40 MPa and the angle of twist 0 is limited to 6 in a length of 3 m. Use G-83 GPa. 2) A simply supported beam AH is subject to a constant distributed load q over the section BC, a moment Mo and a concentrated force P at D. The cross section of the beam is shown below. The parameters are following L-2.5m, q-14 N/m, Mo=55Nm, P=45N, b= 0.05m a) Draw the shear force and bending moment diagrams. Mark the values at the cross sections A, B, C, D, and H, and the maximum and minimum values along the beam. V(x) M(x) L/4 B De Mo L/4 L/4 L/4 H
