Hi i have a question on taking moments physics its quite long.

A garage door is mounted on an overhead rail. The wheels at A an B have rusted so that they do not roll, but slide along the track.
The coefficient of friction is 0.5. the distance between the wheel is 4ft, and each is 1ft in from the vertical sides of the door. The door is symmetrical and weighs 160lb it is pushed to the left at a constanct velocity by a horizontal force P.

(a) if the distance h is 3ft what is the vertical component of the force exerted on each wheel by the track?

(b)Find the maximum value h can have wi
