An 02-series single-row deep-groove ball bearing with a 30-mm bore is loaded with a 2 kN axial load and a 5 kN radial load. The inner ring rotates at 400 rpm. Required:
a. Determine the equivalent radial load that will be experienced by this particular bearing.
b. Determine the predicted life (in revolutions) that this bearing could be expected to give in this application with a 99% reliability.

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?

Asimply supported beam abc of length l has ab of length hl and second moment of area / and bc of length hl and second moment of area i2. determine the strain energy stored in the beam when it is subject to a vertical load f at its midpoint and the consequential central deflection.
