1. The problem statement, all variables and given/known data Hi, I was working on a homework problem and could not resolve it. The problem reads as follows: A ladder that weighs 240N rests against a frictionless wall at an angle of 60 degrees from the ground. A 600-N man stands on the ladder three-fourths of the distance from the top. How much force does the top of the ladder exert on the wall? 2. Relevant equations The equations used are: Στ = τ + τ + etc! τ = F ⋅ L 3. The attempt at a solution 1.) write out a simple free-body diagram with all of the know forces and information displayed. In particular, I illustrated the weights and the angle that was given by the problem. The main difficulty I had was the condition that " man stands on the ladder three-fourths of the distance from the top." Did that mean he was three-fourths along the way on the hypotenuse of the right triangle made by the ladder or along the wall? Another problem I had with this question was what was the relative length of the ladder. The problem did not specify what was the length of the ladder in question. I went with a length of one and used the trig values of the angle for the other sides. I was not able to come up with the answer in the book which was 440N.
