A 7.3 kg ladder, 1.92 m long, rests on two sawhorses, as shown in Figure 20. Sawhorse A, on the left, is located 0.30 m from the end, and sawhorse B, on the right, is located 0.45 m from the other end. Choose the axis of rotation to be the center of mass of the ladder. a What are the torques acting on the ladder? b. Write the equation for rotational equilibrium. C. Solve the equation for FA in terms of Fa. A How would the forces exerted by the two sawhorses change if A were moved very close to, but not directly under, the center of mass?

    A uniform ladder stands on a rough floor and rests against a frictionless wall as shown in the figure. Since the floor is rough, it exerts both a normal force N, and a frictional force f on the ladder. However, since the wall is frictionless, it exerts only a normal force N, on the ladder. The ladder has a length of L = 4.65 m, a weight of W = 50.5 N, and rests against the wall a distance d...

    A uniform ladder stands on a rough floor and rests against a frictionless wall as shown in the figure. Since the floor is rough, it exerts both a normal force N1 and a frictional force f1 on the ladder. However, since the wall is frictionless, it exerts only a normal force N2 on the ladder. The ladder has a length of L = 4.85 m, a weight of WL = 62.5 N, and rests against the wall a distance d...

    A 88 kg window cleaner uses a 10 kg ladder that is 7.3 m long. He places one end on the ground 4.5 m from a wall, rests the upper end against a cracked window, and climbs the ladder. He is 2.9 m up along the ladder when the window breaks. Neglect friction between the ladder and window and assume that the base of the ladder does not slip. When the window is on the verge of breaking, what are...

    A 8.62 -m ladder with a mass of 21.1 kg lies flat on the ground. A painter grabs the top end of the ladder and pulls straight upward with a force of 234 N. At the instant the top of the ladder leaves the ground, the ladder experiences an angular acceleration of 1.87 rad/s2 about an axis passing through the bottom end of the ladder. The ladder's center of gravity lies halfway between the top and bottom ends. (a) What...
