A question came up in physics class that I'm curious about. The question involved a ladder leaning against a frictionless horrizontal surface with a man climbing up it. The ground the ladder was resting on had a friction coefficient and the angle of the lean of the ladder was given. The question asked which point on the ladder was the highest the man could climb before the ladder would slide out from under him. Now, my question to you is this: How does one determind the the components of the forces caused by the weight of a leaning object? The weight vector of an oject always points downard, but an object that is leaning or falling has forces acting upon it in both the X and Y direction, how do I determine these?
