For the Fr force why Base is not 117720 and is 58860 ?

[@pporrasp]

Also, why do you use the trapezoidal distributed load instead of just using the triangular distributed load at the gate, since the gate is not flushed with the wall?

[@86rmb]

As water is incompressible the rest of the water is still acting down on it.

[@pporrasp]

Great video. Shouldn't the reaction Bx be greater than Ax, since the pressure is higher a point B?

[@86rmb]

no, as the centre of pressure (Ft) is acting closer to Ax than Bx. The Centre of Pressure is the point at which the hydrostatic force acts, basically where all the pressure of the water is said to act.

[@immortalgamingkings583]

shouldnt there be vertical reaction forces at A and B as well?

[@connorharris7574]

no, sum of forces in the y=0 and there are no others

[@saltdestroyer]

there is at B, but A is a pin. The one at B is 0 since the sum of forces in the Y has to be 0.

0.75x and its a normal pace haha
