1. The problem statement, all variables and given/known data I have a 3-4-5 right triangle with the 3 as the base and the 5 as the hypotenuse. The corner of the 3 and the 5 is point A The corner of the 3 and the 4 is point B At B, perpendicular to the base is a force of 100lb going down- into the corner. (Fv) At B, Parallel to the base is a force of 100lb going "into" the corner. (Fh) 2. Relevant equations The question is asking: Find the moment of the force with respect to A. 3. The attempt at a solution I am assuming the angles are 53 deg at A, 37 deg at B (and the 90 of course). I am treating this like a torque equation but since the forces are going into the figure. I have no idea where to start. Any help would be greatly appreciated. It's been about 5 yrs since I have done any physics. I am taking a fluid dynamics class to prepare to begin getting my MS in Environmental Engineering (Water) in the fall. Thank you!
