Conduct a preliminary design study to determine a combination of dimensions and lubricant parameters suitable for this application.

1. For the design result you found in solving

a. Find the friction drag torque.

b. Find the power dissipated as a result of friction drag.

2. A hydrodynamically lubricated plain bearing is to be designed for a machine tool application in which a rotating steel spindle must be at least 1.00 inch nominal diameter, the bushing is to be bronze, and the steel spindle is to be lapped into the bronze bushing. The radial bearing load is 40 lb, and the spindle is to rotate at 2500 rpm. The desired ratio of length to diameter is 1.0. Conduct a preliminary design study to determine a combination of dimensions and lubricant parameters suitable for this application.
