A solid steel bar of diameter di = 1.3 in. is enclosed by a steel tube of outer diameter dz = 2.45 in. and inner diameter d2 = 1.95 in. (see the figure). Both bar and tube are held rigidly by a support at end A and joined securely to a rigid plate at end B. The composite bar, which has length L = 29 in., is twisted by a torque T = 4,900 lb-in. acting on the end plate. Tube B Ва End plate (a) Determine the maximum shear stresses Tį and T2 in the bar and tube, respectively. Round your answers to the nearest whole number. T1 = psi T2 = psi (b) Determine the angle of rotation (in degrees) of the end plate, assuming that the shear modulus of the steel is G = 11.4 x 10° psi. Round your answer to three decimal places. (C) Determine the torsional stiffness kr of the composite bar. Round your answer to the nearest whole. [Hint: Use equations below to find the torques in the bar and tube.] GIP, T1 = T (G,Ip + G2IP, kT = k-in.
Axial loads are applied to the compound rod that is composed of an aluminum segment rigidly connected between steel and bronze segments. What is the stress in each materials given that P = 10kN?
The saturated clay sample was weighed in a container and the total weight was 7.4 N. 24 hours 105 degreesAfter waiting in the oven, the container was weighed again, this time it was measured as 5.6 N. The weight of the container is given as 0.7 N. Given the specific gravity of 2.66 for the soil, a) water content b) void ratio c) porosity d) density and e)Calculate the unit weight.
Rigid bar ABCD is supported by a pin connection at A and by two axial bars (1) and (2). Bar (1) is a 30-in.-long bronze [E = 15900 ksi a = 9.4x 10-6/°F] bar with a cross-sectional area of 1.00 in.?. Bar (2) is a 48-in-long aluminum alloy [E = 9200 ksi, a = 12.6 x 10-6/°F] bar with a cross-sectional area of 2.50 in.?. Both bars are unstressed before the load Pis applied.
