Problems 7.42 and 7.43
The driveway gate is hinged at its right end and can swing freely in the horizontal plane
The gate is pushed open by the force P that always acts perpendicular to the plane of the
gate at point A. which is a horizontal distance d from the gate hinge. The weight of the
gate is W = 215 lb, and its mass center is at G, which is a distance w/2 from each end
of the gate, where w = 16 ft. Assume that the gate is initially at rest, and model the gate
as a uniform thin bar as shown below the photo.
