Hello,
I am making a workbench for my mancave, the front edge of the bench is supported by legs that slopes inwards at 78 degrees and the back/rear edge of the bench top is fixed to the wall. How do I calculate the force Q pulling the bench top away from the wall please?
Also is the force Q...
Calculations with 1:
T1sintheta + T2sintheta = W
T1costheta = T2costheta
Calculations with 2:
Wsintheta = T1
Wcostheta = T2
These are not equivalent. Can someone point out the flaw in my logic?
Edit: System is in equilibrium!

what's the Fa and Fb?
my logic is
Fa = Wa - N = mg - ##\frac{N}{\cos \theta}##
so is Fb...
so the ratio is 1. But I know it's wrong. What will make the difference between Fa and Fb?
can anyone give a clue please?
