Consider the torque acting on the ladder about the point where it meets the ground.
Ladder on a wall physics problem.
The coefficient of the static friction μ sw between the ladder and the wall is 0 3 and the coefficient of the static friction μ sf between the ladder and the floor is 0 4.
Homework statement a 70 kg window cleaner uses a 16 kg ladder that is 5 6 m long.
Unconstrained ladder in the þrst problem a ladder is leaning against a wall and sliding under the inßuence of gravity alone.
The center of mass of the ladder is 2 5 m from it s base and the coefficient of friction is 20.
A 5 meter long ladder weighting 200 n rests against a smooth vertical wall with its base on a horizontal rough floor a distance of 1 2 meters away from the wall.
In this case the ladder is on a rough surface and put fairly steeply in against the wall it makes sense that forces and torques will balance.
Neglect friction between the ladder.
In this seventh of the seven part series we will find out a will the ladder slip when th.
Only three forces contribute to this torque.
The weight of the ladder which acts half way along the ladder.
Shows how to use static equilibrium to determine the force of friction between the bottom of the ladder and the groun.
A ladder against a wall.
A suppose that there is no friction between the ladder and the wall.
Static equilibrium the ladder problem.
Taken together provide interesting insights into the ladder problem and resolve the paradox of inþnite speed.
Find the minimum angle that the ladder can form with the floor not to slip down.
The weight of the.
He places one end on the ground 2 0 m from a wall rests the upper end against a cracked window and climbs the ladder.
How far up the ladder can a 600 n person climb before the ladder begins to tip.
D 2 0 m.
Assume this person climbs up so that he stands 2 0 m from the bottom of a ladder i e.
He is 3 5 m up along the ladder when the window breaks.
The formal statement of this problem is as follows.
Be confident in your approach to the physics by clearly articulating why you approach the problem as you do.
You may also have noticed that very little information was provided.
Let be the normal reaction at the wall let be the normal reaction at the ground and let be the frictional force exerted by the ground on the ladder as shown in the diagram.
