Two friends are carrying a 500 N wooden slab along a 45 degrees stairway. The slab is 1.0 m long and 0.40 m high. They each apply vertical upward force (black arrows) on the bottom edges of the box in such a way that the box remains parallel to the stairs as shown in the figure. What are the magnitudes of theforces exerted by the lower and higher friend, respectively?

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,
Fg,
is supported by the force
n
exerted by the floor on the toes of one foot. A mechanical model of the situation is shown in Figure b, where

- 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 FAL at an angle ϕ relative to the horizontal. See the diagram below.The ladder has a length L and makes an angle of θ with respect to the vertical wall. You have a mass, mY, and are a horizontal distance x from the wall. The ladder has a mass of mL. 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,mY,mL,θ,ϕ. Then use the following values to get a number for the magnitude of FAL θ = 34.4 degreesϕ = 26.144 degreesx = 1.612 metersL = 6.2 metersmY = 98.0 kgmL = 32.34 kgarrow_forward0.4 m.
