A torque of 4000 ft-lb is applied in a torsion test on a thin-walled part whose...
Single Cell Torsion (and a little buckling) 2. (20 pts) Suppose we wish to design a minimum weight shaft of Im length to support a limit Torque of 35 kN-m. The material is specified as aluminum 6061-T6 with yield strength of 240 MPa, Young's Modulus 70.0 GPa and Poisson Ratio 0.33. We recognize that for this pure torsion application a thin-walled, hollow circular shaft is the optimum configuration, but what radius and wall thickness will minimize the weight? Determine the...
Question 20 1 points Saved The following is the torque versus angle of twist diagram for a 0.75 inch diameter steel bar tested in torsion. The gage length of the bar is 3 inches. The angle of rotation and torque at points and Pare (0.8 radian, 1500 in-Ib) and (11.3 radian, 4000 in-lb) respectively. The power-law curve fitting relation for the data above the yield point is given by T-329800.21, where is in in-Ib and is in radian. Torque T...
