The masses of the blocks are mA = 30 kg and mB = 70 kg. Between all of the contacting surfaces the coefficient of static friction is 0.1. 1. What is the largest force F that can be applied without causing the blocks to slip? 2. What is the reaction between the two blocks? 3. What is the reaction between the floor and block B

Need help finding the second part of the question.

Find Frictional Force as well

consider the mass and pulley system in the attached file. mass m1 = 29 kg and mass m2 = 12kg. the angle of the inclined plane is given and the coefficient of kinetic friction between mass m2 and the inclined plane is uk = 0.12. assume the pulleys are massless and frictionless when mass m2 moves a distance 4.94 m up the ramp, how far downward does mass m1 move? d= ?

A 150-lb block rests on a horizontal floor. The coefficient of friction between the block and the floor is 0.30. A pull of 40 lb, acting upward at an angle of 30° to the horizontal, is applied to the block. Determine whether or not the block will slide. - Draw Free-body diagram  - Solve most simple way  - use the formula Fmax= Ms (N)

I need a process for this problem

Six 5 N blocks are stacked vertically. The coefficient of static friction between the blocks is µs = 0.20. Determine the horizontal force that must be applied to the fifth block from the top of the stack, in order to slide it out without moving the other blocks.

1. The light bar is used to support the m kg block in its vertical guides. If the coefficient of static friction is 0.30 at the upper end of the bar and 0.4 at the lower end of the bar, m kg a. Find the friction force acting at each end for x = 75 mm. b. Find the maximum value of x for which the bar will not slip. 218 kg m = А l = 318 mm Figure 1.

To determine the minimum required coefficient of friction , between the wall and spool such that the spool does not slip, which of the following statements are true? (Select all that apply.) 0.6 m- 000 60° 0.3 m Frictional force at A acts upward Frictional force at A acts downward Frictional force at A is equal top, NA Frictional force at A is greater than , NA Frictional force at A is less than , NA Normal force at A acts to the left Normal force at A acts to the right

If the coefficient of static friction at the contact points A and B is μs = 0.4, determine the following if the girl is 75-lb and the plank is 20-lb:1. Reaction at A (in lb) (ANSWER: 90.4) and Reaction at B (in lb) (ANSWER: 60.2). 2. The minimum distance d (in ft) can a girl stand on the plank without causing it to slip. (ANSWER: 2.23).
