Question: a square block 200mm3 and mass 1kg is pulled up...
A square block 200mm3 and mass 1kg is pulled up a plane inclined at 45o to the horizontal over a thin film of SAE 10W-30 oil at 40oC. The oil film thickness is 20×10−6m, and the velocity profile in the oil film is linear.
1. Sketch the free body diagram.
2. If a force of 10N is applied to pull the block up the incline, find the steady-state speed of the block.
