I plan to build a hatch door in one side of my shed. The plan is that the hatch door will be hinged at the top long edge. The hatch door will open from the bottom long edge. The hatch door will open out and up to a horizontal position (possibly slightly past horizontal). My question is what lifting force will be required to lift the door, what force will be required to keep the door in the open position, what forces (value and direction) will be exerted on the hinge during lifting and open. Sizes have not been decided yet so assume door size; horizontal length = L, vertical height = H, weight of door =W. Gravity here is normal. Any help, advice or insight would be appreciated.
