A solid brass shaft is loaded as shown below by two torques TB segments are LAB = 750 mm and LBC = 600 mm. = TB Тс A dAB B dBC C LAB LBC 1100 Nm and TC: = 400 Nm. The lengths of the two For brass, G = 41 GPa. Neglect the effect of any stress concentrations. Determine the smallest diameters dдB and dBC for which an allowable shear stress of 60 MPa is not exceeded. Express each diameter as an integer in units of mm.

Load P is applied to joint D and the temperature increases by 50 °F. There are two steel (E = 29*10^6 psi; a = 6.5*10^-6/°F) AD and DC and a bronze (E = 16*10^6 psi; a = 9*10^-6/°F) BD with a length of 50 inches. Each bar is a 0.75 inch diameter. Find the deformation of every rod, the displacement at D, and the stress in each rod.
