Hello professor, your voice is so professional .❤

In problem 2, the normal to the gate had vertical components, but the summation of forces resulted in no vertical forces because of the weight of the water. If that is a correct interpretation, please explain? (This seem to be the intuitive result, but contradicts the idea that the force is normal to the surface?) Thank you. Your videos are great for self-teaching.

Suppose the gate was submerged such that the free surface was height H above the top of the gate with the section above the gate being a vertical wall (think upside down P). Would the vertical portion of the pressure force still be the weight of the water within the control volume? The horizontal portion would still be similar to the current solution where it would be gamma*width*total height*gravity.

Hello Professor, may i know why F(AB) is not considered in the moment ?

[s.dhineshselvarajan]

The line of action of Fh and Fv will pass through the centre of circle. But you have located somewhere.

[grassygrandma]

why is there not a weight force of the gate when using the FBD of the gate in the first example?

[iamdanishhavocx]

how did u get the depth as 1 m in the first example, the image was in 2d

Where is the vertical force acting on the top of the free body in no 2 prblm 7:55
