Fig. ass Mi slides on a 45° inclined plane of height H as sh connected by a flexible cord of negligible mass over a small pulley (neglect its mass) to an equal-mass M2 hanging vertically as shown. The length of the cord is such that the masses can be held at rest both at height H/2. The dimensions of the masses and the pulley are negligible compared to H. At time t = 0 the two masses are released. The acceleration of M2 downward is 1.43 m/s^2 and Box 2 will strike the ground at t = 0.84/H. A) Derive an expression for the tension in the pulley with the two masses and derive an expression for the tension if M1 is not attached to the rope anymore. My 45° M₂ H/2

A 6-m long ladder has a mass of 13 kg., and its center of gravity is 2.4 m from the bottom along the ladder. The ladder is resting on a 5° upward sloping floor at A and on a wall inclined to the right at 5° from the vertical at B, so that it makes an angle of 60° with the horizontal. How far up along the ladder can a 78-kg man climb before the ladder is on the verge of slipping? The angle of friction at all contact surfaces is 15°. Also determine the total reaction at A and B in Newton. Note: Point A is at the left of point B.
A heavy cabinet with a mass of 135kg is transported on the truck platform.

A 30kg mass is tied to a uniform rod whose mass and length are 80-kg and 8-m, as shown below. The rod is attached to the floor via a hinge and makes an angle of 70° relative to the ground; a massless string is also attached to the rod at the ¼ point of the rod and makes an angle of 20° relative to the horizontal. What tension must be provided by the rope so that the system remains in stationary? If at some point the string breaks, what will be the angular acceleration of the system the instant that the string breaks?
