Statics Example: 2D Rigid Body Equilibrium 2

[mondomola]

Isn't it important that the angle between the straight vector joining the point about which you are studying torque and the point where a force is applied and the vector of that force is 90 degrees in this example? Otherwise you would multiply it by the sine of that angle, no?
