A member in bending due to the 40 lbforce at the right end is to be sized. Say the thickness is 0.25 in, but the height in the plane is to be determined. Let the maximum allowable bending stress be 12,000 psi. Consider three cross-sections: (a) midway between the supports, (b) at the roller, and (c) midway between the roller and the load at the end. For each cross-secti

Asolid cylinder is concentric with a straight pipe. the cylinder is 0.5 m long and has an outside diameter of 8 cm. the pipe has an inside diameter of 8.5 cm. the annulus between the cylinder ad the pipe contains stationary oil. the oil has a specific gravity of 0.92 and a kinematic viscosity of 5.57 x 10-4 m2/s. most nearly, what is the force needed to move the cylinder along the pipe at a constant velocity of 1 m/s?
