1. The problem statement, all variables and given/known data
A_________B____________Wd_________Wp_
|--1.2m--|----1.2m------|---2.2m-----|
Above is a diving board with 2 weights on it. determine the reactions of A and B
wd= 36kg = weight of diving board
wp= 54kg = weight of person standing on diving board
point A = pin support
point B
2. Relevant equations
Ok so the sum of the forces in the x and y directions are as follows x = 0 because their are no x components. Y = -54gk(9.81m) + (-36kg(9.81m)) = 529.74 + 353.16 = -882.9N. After this i do not know what to do.
3. The attempt at a solution
Answers are Ax= 0, Ay = -1870N, By=2740N
