Calculate the reaction forces at B and D
See attached jpeg.
The Attempt at a Solution
sum of vertical forces
By + Dy = 7 + (9*5)
Do I then solve for the moment about D or A or B?
for moment about D i have: -Dy -7 -(9*5)+9By+(12*2)=0
is this correct, please explain to me the process of and how I should go about these problems
Any advice is appreciated, thankyou.
