Hydrostatic Force Calculations

The video tutorial explains how to calculate the hydrostatic force on a submerged triangular plate. It begins by setting up the problem and dividing the plate into small slices. The force on each slice is approximated using geometry, and the total force is found by summing these forces and integrating. The tutorial concludes with a recap of the process and a final calculation of the force in Newtons.
