Determine force P for impending motion to the left if the coefficient of friction for all surface is 0.15. 100 kg A 50 kg 50°

Determine the minimun force that is needed for F to move B to the right. B has weight 100 N, A has weight 10 N. Friction coefficeint for all contact surfaces including peg is 0.3

I UBC Engineering The 4 kg block sits on the edge of a disk with a radius of r = 1.25m. a. Assuming the block does not slip, what would be the force of friction between the block and the disk if the disk is rotating at a constant angular velocity of rad 1.1 ? S F = 6.05 * N b. If the disk then begins to slow down and the coefficient of static friction between the block and the disk is μs = 0.278, what is the magnitude of the maximum initial angular decceleration that would not cause the block to slide on the disk? Maximum a = 2.18 ☑ rad $2
