1. The problem statement, all variables and given/known data There is a copy of the problem in the picture with the graph. 2. Relevant equations M = F*d, M = Fxr, F_x = Fcos(theta), F_y = Fsin(theta) where theta is measured off the positive X axis, 3. The attempt at a solution I tried splitting the force vector into X and Y components and then multiplying each of those by the perpendicular distance to the corresponding axis. My understanding from in-class examples was that these two values should sum to the moment about the given point. All I know is that I get the wrong answer: M = 1*30cos(26.57) + 4*30sin(26.57) = 80.51 According to my book, I should get 83.2. Any help is greatly appreciated!
