Homework Statement
Water is retained in a 1.25 rectangular section channel by a sluice gate. This gate can pivot about its base, the depth of the water is 1.5m and the density of the water is 1000kgm^-3. You must find the tension in the horizontal retaining cable attached to the top of the gate.
Homework Equations
Thrust: F= pgAh
Gravity = 9.81
The Attempt at a Solution
Provided data:
Retained water 1.25
Density: 1000kgm^-3
Depth: 1.5m
Gravity: 9.81
So this is what i did, first i found the thrust of the gate so:
F=1000 x 9.81 x 1.5 x 1.25 = 18393.75 so 18.3 x 10^3 or 18.3 kN
I'm not sure though if this is right or what to do next to find the tension, could someone help me on this please
