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)
