3. A shaft is composed of five segments; AB, BC, CD, DE, and EF is fastened to rigid supports and is being subjected by Torques; Te at B, Tc at C, To at D, Tɛ at E. Segment AB has a diameter of 25 mm, G = 200,000 MPa, Segment BC has a diameter of 20 mm, G = 180,000 MPa, Segment CD has a diameter of 28 mm, G = 220,000 MPa, Segment DE has a diameter of 32 mm, G = 280,000 MPa, Segment EF has a diameter of 15 mm, G = 140,000 MPa. 1.3 m 07m 1.6 m 1.0m a) Determine the maximum shearing stress at EACH segment. b) Determine the angle of rotation at EACH segment. TORQUE TB = 330 N-m TORQUE TC = 830 N-m TORQUE TD = 1130 N-m %3D TORQUE TE = 1430 N-m Please solve completely with figures and torque diagram, Thank you!

The torsional assembly consists of solid 2.3 in. diameter aluminum [G = 4,000 ksi] segments (1) and (3) and a central solid 2.7 in. diameter bronze [G = 6,500 ksi] segment (2). Segment lengths are L1 = L3 = 38 in. and L2 = 68 in. Concentrated torques of TB = 2T0 and TC = T0 are applied to the assembly at B and C, respectively. If the rotation angle at joint B must not exceed 3.9°, determine: (a) the maximum magnitude of T0 that may be applied to the assembly. (b) the maximum shear stress magnitude in aluminum segments (1) and (3). (c) the maximum shear stress magnitude in bronze segment (2).

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.
