Hello,
This is probably really simple but i don't know if this is the right way to work out the answer
i have attached an image containing the problem.
I know how to get F2 :
Taking moments about A:
F2 Cos 60 = 1500
F2 = 3000N
But then it says to find F1 using the principle of moments, and the only way i can get the answer is:
taking moments about B: (F1 x 1.5) = (1500 x 2.5)
F1 = (1500 x 2.5) / 1.5
F1 = 2500N
is this right?
Thanks alot
Cain
