QL3P2 Determine an appropriate size for a square cross-section solid steel shaft, in inches to four significant digits, to transmit a torque T = 29,178 lb-in if the maximum allowable shear stress is 15 kpsi. Note: for b = c or b/c = 1, = 0.208 Show your answer in the form: b = ---- in

A solid brass shaft is loaded as shown below by two torques TB- segments are LAB = 700 mm and LBC 600 mm. A dBc = dAB mm LAB mm B Com dBC For brass, G = 41 GPa. Neglect the effect of any stress concentrations. LBC Determine the smallest diameters dAB and dBC for which an allowable shear stress of 50 MPa is not exceeded. Express each diameter as an integer in units of mm. dAB To 1100 Nm and Tc = 300 Nm. The lengths of the two Determine the magnitude of the total angle of twist in the shaft caused by the two applied torques for the diameters found previously Express your result in units of radians with five decimal places of accuracy. PAC = rad

A alm T 1.20 m T B 1.20 m C 3 T The 60 mm diameter shaft is made of 6061-T6 aluminum having an allowable shear stress of Tallow 80 MPa. Find the corresponding angle of twist of disk A relative to disk C. Note: You will need to calculate the maximum allowable torque T first. Provide your answer for angle of twist in radians with 3 significant figures after the decimal point.
