A rectangular sluice gate, 3 m high and 2.4 m wide, can slide up and down between vertical guides. Its vertical movement is controlled by a screw which, together with the weight of the gate, exerts a downward force of 4000 N in the centre-line of the sluice. When it is nearly closed, the gate encounters an obstacle at a point 460 mm from one end of the lower edge. If the coefficient of friction between the edges of the gate and the guides is f=0.25, calculate the thrust tending to crush the obstacle. The gate is shown in Fig. 4.4.
