A refrigerator is at rest on a level floor. Attempting to slide it across the floor, you exert a horizontal pushing force P at a height y above the floor, as in the figure. If y is too large, the refrigerator will tip instead of sliding. Find the largest value of y that makes the refrigerator slide without tipping if its mass is M = 122 kg, its center of mass is located where d = 0.32 m and h = 0.99 m, and the coefficient of static friction between the refrigerator and the floor is μs = 0.33. [Hints: Use the equilibrium conditions to place the refrigerator on the verge of both sliding and tipping (but not doing either). When the refrigerator is on the verge of tipping, the normal force will act at its lower front corner.] y = P Y m M cm- h -d-

You are working in an ice skating rink and have been asked to hang a new banner on the wall. Your friend is helping you so that the ladder does not collapse by exerting a force F_AL at an angle ϕ relative to the horizontal. The ladder has a length L and makes an angle of θ with respect to the vertical wall. You have a mass, m_Y, and are a horizontal distance x from the wall. The ladder has a mass of m_L. Because the wall is slick, and the ice on the floor is slick, the frictional forces acting on the ladder are negligible. Find a formula for the magnitude of the force that your friend must exert to keep the ladder from falling, in terms of the following variables: x,L,m_Y,m_L,θ,ϕ. Then use the following values to get a number for the magnitude of F_AL. θ = 30.3 degrees ϕ = 23.028 degrees x = 1.491 meters L = 7.1 meters m_Y = 86.0 kg m_L = 42.14 kg Find the magnitudes of: F_AL, normal force of the wall on the ladder (N_WL), and normal force of the floor on the ladder (N_FL).
Lizzy is training on the trapeze when a slight accident occurs. As a result, she is now hanging from the middle of a 60 m safety rope connected to the ceiling on one end and held by a strongwoman from the circus on the other end. She has a mass of 50 kg and the part of the rope connected to the ceiling makes an angle of 55° with the vertical. The part of the rope that connects Lizzy to her fellow circus artist makes an angle of 20° above the horizontal (the strongwoman is above Lizzy). As long as Lizzy remains stationary, what is the tension in both parts of the rope?
Could I please get some help with this problem please and thank you!
When a person stands on tiptoe (a strenuous position), the position of the foot is as shown in Figure a. The total gravitational force on the body, F, is supported by the force g' n exerted by the floor on the toes of one foot. A mechanical model of the situation is shown in Figure b, where T is the force exerted by the Achilles tendon on the foot and R is the force exerted by the tibia on the foot. Find the values of T, R, and 0 when F = n = 780 N. (For 0, enter the smaller of the two possible values between 0° and 90°.) -Achilles tendon Tibia 15.0° 18.0 cm 25.0 cm b T = R =
The block shown in (Figure 1) has a mass of m = 100 kg, a height H = 1.4 m, and width L = 2 m. It is resting on a ramp that makes an angle = 38 ° with the horizontal.

A system comprised blocks, a light frictionless pulley, and connecting ropes is shown in the figure. The B block has a mass of 9.3 kg and is on a perfectly smooth horizontal table. The surfaces of the A block, which has a mass of 8.2 kg, are rough, with μk=μk= 0.25 between the block and the table. If the C block with mass 9.9 kg accelerates downward when it is released, find its acceleration.
A Block A with mass mĄ rests on a horizontal tabletop, while block B with mass mg hangs from a string of negligible mass that passes over a pulley and attaches to block A, as shown above. The pulley has negligible mass and rotates with negligible friction about its axle. The blocks are at rest due to friction between block A and the tabletop. The coefficient of static friction between block A and the tabletop is u (mu), where u < 1.
In the figure below, a climber with a weight of 720.6 N is held by a belay rope connected to her climbing harness and belay device; the force of the rope on her has a line of action through her center of mass. The indicated angles are e = 35.5° and o = 29.5°. If her feet are on the verge of sliding on the vertical wall, what is the coefficient of static friction between her climbing shoes and the wall?
A 1.5 kg block is connected by a rope across a 50-cm-diameter, 2.0 kg pulley, as shown. There is no friction in the axle, but there is friction between the rope and the pulley; the rope doesn’t slip. The weight is accelerating upward at 1.2 m/s2. What is the tension in the rope on the right side of the pulley?
Q4.2. A springboard-type diving board is built from high grade aluminum. This particular board has a mass of 65 kg and is 3.85 m long. 33.8 cm wide, and 5 cm thick. (Aside: Most springboards start thick on one end, then get thinner as it moves to the other end. For this problem, assume the springboard has a constant thickness) One end of the springboard is attached to a hinge. The hinge lets the springboard move up and down, but keeps it from sliding out of place. 1.1 m away from the hinge, the springboard rests on (but is not attached to) a fulcrum. A diver with a mass of 65 kg stands on the far end of the springboard (opposite from the hinge), ready to begin their dive. Hinge Fulcrum Note: the measurements for this problem were taken from the springboards used in the 2016 Summer Olympics, 3 m Springboard event.
A 20 kg dog stands on a 40 kg platform that is supported by two ropes. One rope is attached to the right edge of the platform and the other is attached 50 cm from the left edge of the platform. The dog sits 50 cm from the right edge of the platform. A 5.0 kg cat jumps up, but is wary of the dog abs stays all the way on the left edge. The platform is 2.0 m long. What is the tension in each rope?
