The figure shows a roll-off truck ramp for discharging loaded containers. The 120-Mg loaded containers may be treated as a homogeneous rectangular solid with mass center at G. In the position shown, the pair of wheels at A are blocked, and the brakes of the truck are applied to prevent movement of the truck. If the wheels at A are suddenly released to allow the container to roll, calculate the total friction force $F$ applied to the truck wheels immediately after wheels A are unblocked. Ans. $F = 340kN$
