Using the distortion-energy and maximum- shear-stress theories determine the factors of safety for the following plane stress states: (a) a, 180 MPa, a, 180 MPa, T., (b), (e) a, (d) T., 150 MPa 100 MPa 100 MPa -160 MPa, Ty=100 MPa Q3: The bar below is made of carbon steel (1035-hot rolled) and is loaded by the forces F = 0.55 kN, P = 8.0 kN, and T = 30 N m. Compute the factors of safety, based upon the distortion-energy theory. Q2: for the shaft shown below answer the following: 1. Find the factor of safety in point H if the shaft is made from carbon steels 1030 hot rolled and the shaft diameter is 32 mm. 2. Find the diameter of the shaft if it made from wrought-aluminum alloy 2024 heat treated and the factor of safety is 2. 3. Select suitable carbon steel alloy for that shaft if its diameter is 25 mm and factor of safety required is 1.5. 0.2 Q4: The figure shows a shaft mounted in bearings at A and D and having pulleys at B and C. The forces shown acting on the pulley surfaces represent the belt tensions. The shaft is to be made of cost iron (class 40) using a design factor N = 2.8.
