looking at the top view of a door that is 1.68 m wide, Two forces are applied to the door.
Hinge, angle a is at halfway point, pointing up and right 55 degrees, Angle b is at edge pointing down and left 55 degrees.
Both forces at the angles are 12N
My crappy illustration:
What is the magnitude of the net torque on the door with respect to the hinge?
I thought since they are pulling opposite directions they would be:
torque of a minus torque of b, (or vice versa) but apparently my answer is wrong.
I've tried several other ways, but none with an answer that matches one of these.
I have 5 choices:
Edit: forgot my forces!
