1. The figure shows the cross section of a rectangular gate 4 m high and 6 m long (perpendicular to the paper) which blocks a fresh-water channel. The gate has a mass of 8.5 Mg and is hinged about a horizontal axis through C. Compute the vertical force P exerted by the foundation on the lower edge A of the gate. Neglect the mass of the frame to which the gate is attached.

2. The horizontal steel shaft with two diameters is welded to the fixed block at A. Construct the dia-grams of shear and moment in the shaft due to its weight. Determine the values of the shear force and bending moment at the discontinuity in diameter.
