Gripper C of the industrial robot is accidentally subjected to a 60 lb side load directed perpendicular to BC (see attachment). The lengths of the robot's links are AB = 22 in and BC = 18 in. By using the moment components method, determine the moment of the force about the center of joint A.

M = Fd (d is the lever arm)

I'm not sure what angle to use when calculating the components of the 60 lb force. Is the 60 lb force at a 140° angle with the coordinate plane given at point A? Since this is the first step of the problem, I want to make sure I'm doing it correctly.
