Torque

Torque is the rotational equivalent of linear force in physics and mechanics. Based on the course of study, it is also known as the moment of force, rotational force, or turning effect.

Question

Part A
An 88 kg person stands on a uniform ladder 4.0 m long, that
weighs 90 N, as shown in the figure(Figure 1). The floor is rough;
hence, it exerts both a normal force, f1, and a frictional force, f2,
on the ladder. The wall, on the other hand, is frictionless; it exerts
only a normal force, f3.
Using the dimensions given in the figure, find the forces exerted on the ladder when the person is halfway up the ladder.
Express your answers using two significant figures separated by commas.

Why is the following situation impossible? A barge is carrying a load of small pieces of iron along a river. The iron pile is in the shape of a cone for which the radius r of the base of the cone is equal to the central height h of the cone. The barge is square in shape, with vertical sides of length 2r, so thatthe pile of iron comes just up to the edges of the barge. The barge approaches a low bridge, and the captain realizes that the top of the pile of iron is not going to make it under the bridge. The captain orders the crew to shovel iron pieces from the pile into the water to reduce the height of the pile. As iron is shoveled from the pile, the pile always has the shape of a cone whose diameter is equal to the side length of the barge. After a certain volume of iron is removed from the barge, it makes it under the bridge without the top of the pile striking the bridge.

Hi please help: An 88kg person stands on a uniform 5.6kg ladder that is 4.0m long. The floor is rough, hence, it exerts both a normal force, f1, and a frictional force, f2, on the ladder. The wall, on the other hand, is frictionless, it exerts only a normal force, f3. Using the dimensions given, find the magnitude of f1, f2, and f3. Express answer using two significant figures and as kN as units.

Two students pull with force 196 N each to the light, four students pull with force 98 N each to the left, five students pull with force 62 N each to the left, three students pull with force 150 N each to the right, and one student pulls with force 250 N to the left. Assuming the positive direction to the tight, express the net pull on the knot in terms of the unit vector. How big is the net pull on the knot? In what direction?
