For the situation shown in Fig 429, what is the minimum coefficient of static friction between the block and the surf that will keep the block from moving? (F_1=5.3 N, F_2=3.1 N, and m_2 = 5.0 kg) .5 .15 26 .001
the coefficient of static friction between block A and its
incline is 0.27. What must the minimum coefficient of static
friction between block B and its incline be if the blocks are in
equilibrium? The mass of block B is twice that of block A. If the
coefficient of friction is less than its minimum, in which
direction will the blocks slide?
assume angle a = 35 degrees and angle b = 35 degrees

A heavy sled is being pulled by two people. The coefficient of static friction between the sled and the ground is μs = 0.595 and the kinetic friction coefficient is μk = 0.403. The combined mas of the sled and its load is m =276 kg. The ropes are separated by an angle φ = 27 degrees, and they make and angle of θ = 30.8 degrees with the horizontal. assuming both ropes pull equally hard, a) what is the...

The uniform 45-lb beam is supported by the rope which is attached to the end of the beam, wraps over the rough peg, and is then connected to the 90-lb block. (Figure 1) PartA If the coefficient of static friction between the beam and the block, and between the rope and the peg, is , 04, determine the maximum distance that the block can be placed from A anc still remain in equilibrium. Assume the block will not...
The coefficient of static friction between the m = 3.85-kg crate and the 35.0° incline of the figure below is 0.325. What minimum force F must be applied to the crate perpendicular to the incline to prevent the crate from sliding down the incline? N
Blocks B has a mass of 20 kg and block C has a massof 15 kg. The coefficient of static friction at thecontacting surfaces is 0.2. Block A is suspended by arope that passes over a fixed cylinder and is attachedto block B. The coefficient of static friction betweenthe rope and the cylinder is 0.25. What is the largestmass block A can have without causing block B to slipthe left?
A particle slides down a fixed rough plane of coefficient of friction u. If the plane is inclined at angle a to the horizontal and the body falls from rest at a vertical height h at the top of the plane to acquire a speed V at the base of the plane find u.
Determine the minimum coefficient of static friction between the disk and the surface so that the disk will roll without slipping. Neglect the mass of the pulleys. Take the touching point of the disk and the surface as IC and work from there. For the disk,
