- The pressure distribution over the base of a concrete (S =2.4) dam varies linearly, as shown in figure ,producing an uplift. Will the dam topple over (sum moments of all forces about the bottom, right-handcorner)? Use:(a) H =45 m(b) H = 60 m(c) H = 75 mStep 2 1st condition Bending moment at hinge D =0 Rc*2 = (3*2)*(2/2) Rc = 3 KN Rc = 3 KN (upward) could you explain where these numbers coming? Why that divided by two? and is formula like this: 3kN/m*2m*2m/2m? 2nd condition Bending moment at hinge F =0 RB*2= (3*4)*(3+4/2)-3*7 RB = 19.5 KN RB = 19.5 KN ( upward) Same this formula If you can explain this like drawing this on paper and write where all meters and number come, that would be help me.
