Question

A 180-lb overhead door consist of a uniform rectangular panel. One half of the door is shown in the diagram; therefore, W in the diagram is 90-lb.

The door is supported at point A by cable AE, and by a frictionless rollers at A and B. The roller at A is free to move in a horizontal channel, and the rollat at B is free to move in a vertical channel. The door is in equilibrium at the position shown, where Theta=41*.

(a) Draw the FBD for the half of the door shown.
(b) Find the tension in cable AE
(c) Find the reaction at roller A and at roller B
