A ladder is leant against the wall.
Ladder on a wall physics problem.
Consider the torque acting on the ladder about the point where it meets the ground.
In this seventh of the seven part series we will find out a will the ladder slip when th.
The formal statement of this problem is as follows.
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.
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.
You may also have noticed that very little information was provided.
