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.
Figure P7.16
Given that a force of P = 20 lb is applied at the center of mass of the gate (i.e., d = w/2), determine the reactions at the hinge O after the force P has been continuously applied for 2 s.
