Homework Statement
I couldn't get the forces in equlibrium in this question
Homework Equations
The Attempt at a Solution
VA + VD = 35(3.5) + 10+15 = 147.5
sum of moment about D = -35(3.5)(1.75+ 3.7) +15(1) + VA(3.5 + 1.7+ 2) = 0
VA = 90.6upwards
Sum of moment about C = -35(3.5)(1.75+1.7) +10(0.7) -VD(2) +15(3) =0
VD = -185 ( downwards) ,
So, VA + VD = -185+ 90.6 = -94.4
So , VA + VD = 90.6 -185 = -94.4N , which is not 147.5N , which part of my working is wrong ?
