Question

A 4m ^ 2 plate of 18 gauge steel moves forward at a speed of 2m / s, while the base of the conveyor belt moves in the opposite direction at a speed of 0.5m / s. Between the conveyor belt and the plate is a 2.5mm thick layer of wax with a viscosity of 2 Pa-s.
Determine:
a) The pressure under the steel plate
b) The necessary force necessary to move the steel plate to the right.

Additional data (plate surface density is 4.99kg / m ^ 2 and thickness is 0.0478 in)
