## Homework Statement

I have to find the forces FGB FCB AND FGH

http://desmond.imageshack.us/Himg696/scaled.php?server=696&filename=img59wa.gif&res=medium

P1 = 5 kN, P2 = 10 kN, JY = 21.25 kN

a1 = 2 m, a2 = 1 m, a3 = 0.5 m, a4 = 1 m, a5 = 2.5 m

Angle FGH makes with the horizontal is: 26.57 degrees

Angle FGB makes with the horizontal is –tan-1(1.5/2)

## Homework Equations

## The Attempt at a Solution

Sum the forces up and down = 5+10 -21.25 +FGHsin26.57 - FGB sin38.87 = 0Then summing moments =

2x10 - 2 x 21.25 +(a2+a3+a4)FGHcos26.57 + FGB cos 38.87= 0

I don't get what i can do from here and I am a bit stuck and i don't no if the force Fcb would have an effect??
