Chapter 13.4, Problem 42P

Block A has a mass mA and is attached to a spring having a stiffness k and unstretched length l0. If another block B, having a mass mB, is pressed against A so that the spring deforms a distance d, show that for separation to occur it is necessary that d > 2 μ k g ( m A + m B ) / k , where μk is the coefficient of kinetic friction between the blocks and the ground. Also, what is the distance the blocks slide on the surface before they separate?

2. The 70-kg door is to close automatically using torsional springs 0.4 m mounted on the hinges. If the torque on each hinge is M = k0, where 0 M is measured in radians, what value k should I be looking for in each of two torsional springs? I desire the door to close as quickly as possible, 1.5 m but to have its speed not exceed 2 rad/s at any time. The door can be opened a maximum of 0 =120°. 0.4 m M 1.2 m
PIN 500 N/m, = Block A has a mass of mд = 3 kg and is firmly attached to a spring with spring constant k which is originally uncompressed. Then, block B with a mass of m³ = 2 kg is pressed against A with a steady force of F 100 N until static equilibrium is reached, as shown in the above figure Determine Suddenly, force F is removed. If B has a coefficient of kinetic friction of μ = 0.2 with the ground (while A's contact with the ground is frictionless). F = a. The force A exerts on B just before the force F is removed b. The force A exerts on B just after the force F is removed c. The speed of block B when it first begins to separate from A d. The distance block B travels before it again comes to rest F = || A V= d = N N B m S m F
