1. The ramp is used as passengers board a small com- A muter airplane. The total mass of the ramp and six passengers is 750 kg with mass center at G. Determine the force in the hydraulic cylinder AB and the magnitude of the pin reaction at C.
2. Determine the cutting force F applied by the blade DE to the bar at G in terms of the force P applied to the handle of the heavy-duty cutter. Assume that the cutting force F is perpendicular to the lower edge of the blade DE.
