To determine the maximum shear force that can be applied to two shafts of varying cross sections: a solid square shaft and a hollow square shaft.
Learning Goal: To determine the maximum shear force that can be applied to two shafts of varying cross sections: a solid square shaft and a hollow square shaft. The two square cross sections shown below (Figure 1) are each subjected to a vertical shear force, V. The side length of each cross section is s = 6.75 in and the side length of the hollowed-out portion of the second cross section is r = 4.00 in. The maximum allowable shear stress in...

2. A circular shaft is mounted in a bearing as shown. There is a small gap between the stationary inner shaft and the outer rotating bearing filled with a viscous, incompressible Newtonian fluid. The shaft turns with a constant rotation rate ω (in rad/sec) due to the downward motion of the attached weight pulling on the cord attached to a the outer bearing (see figure) of radius R Hint: If the gap between the shaft and bearing is small compared...
