###### Question:

Don’t do the problem; I’m just trying to figure out why the coordinates for the resultant force are at the centroid. Wouldn’t the F1 pull the y location of the resultant force down? I can seem to wrap my head around how the pressure on the wall is so high in the Y direction.
Problem 3 (20 points) The sea wall in the following figure is in the form of a semi-parabola. The density of the water is 1050 kg/ml. Hint: The last page has centroids for several shapes. a) Determine the components of the resultant force acting on I meter of its length (out of the page). FH = F, = 8 het = (1050kg/m3)(9.81 %)(4mX8xYA H = 329.6 kN| Fv =W=8+ he = /H A = H (lm) +(1050 KY/m3) (9.817/3)(5.33m) Fr=54.9kN) V=73(8 m/2m) (im) from * = /Bablim) al carrer centros page b ly ' fra From t = 5.33m3 b) Determine the x and y coordinates of the location where the resultant force acts using the coordinate system in the figure. centroid a page x0,0) Ye Y = 1/3H = 1/318 m) =(2.6 X= 3/4b = 3% (2m) = 15m in the negative x dir [X=-1.5m)
