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...
Q3: According to your textbook, what is the coefficient of viscosity for water at 100°C? Give your answer in terms of Pa·s. Q4: A tensile test uses a test specimen that has a gage length of 50 mm and an area = 211 mm2. During the test, the specimen yields under a load of 95,191 N. The corresponding gage length = 50.24 mm - this is at the 0.2 percent yield point. The maximum load of 160,342 N is reached...
