A 1-kg of wood is pressed against a vertical wall (µs= 0.25) by a force inclined 40º upward with respect to the vertical axis.

A 1-kg of wood is pressed against a vertical wall (µs= 0.25) by a force inclined 40º upward with respect to the vertical axis. Determine the maximum force which can start the motion of the block.   F = (0.25)(9.8 cos40)+(9.8 sin30) / cos(4) – 0.25(sin30)= 7. 77 N

The coefficient of friction between the sole of a shoe and a tile span roof is 0.36.

The coefficient of friction between the sole of a shoe and a tile span roof is 0.36. What minimum slope of the roof can start slipping?   Θ = tan Θ = tan 20° = 0.36

A 60 kg package rests on the level floor of a warehouse.

1.) A 60 kg package rests on the level floor of a warehouse. If the coefficients of static and kinetic frictions are 0.56 and 0.37 respectively, what horizontal pushing force is required to (a) start the package’s motion? (b) slide ...
