length L = 3 m, width b = 4 The gate creates an angle on 30° horizontal. It is assumed that the gate can rotate as a stiff system without friction around A. Movable mass on the gate M = 5000 kg in the distance x from B Gate mass m = 6000 kg Density of water = 997 kg/m^3 Gravitational acceleration = 9,81 m/s^2 L = 3 m 0 = 30° Water M a) Find the distance x so...
QUESTION 2 (10 marks) A rectangular gate of width w = 2m, and length L - Xm, and of uniform thickness so that the centre of mass is located at the centroid, holds back a depth of water at 15°C as shown. The water surface is at the same height as the gate hinge. Find the minimum weight of the gate so that the gate remains closed. 8 = 30° L=4m Water Wm
(b) A rectangular panel of width equal to 1 m is kept in place through the system shown in Figure 2. If is equal to 3 m, find (i) the force on the gate due to the water pressure (ii) the location where this force acts (iii) the tension in the cable to balance the force due to pressure. Note that the gate is hinged at [4 Marks] [2 Marks] the pivot, thus the tension in the cable can be...

1. The width y of a flood defence gate is 6 m and the profile is given by z 3x as shown in Figure 1. If water is retained to a depth of z 3 m on the upstream side of the gate, determine forces Fx and Fz acting on the gate. Hence (or otherwise) find the moment M acting about the base of the gate. gate Figure 1 water 3 m 1. The width y of a flood defence...
