## Homework Statement

**Find stress or force in member AE**

## Homework Equations

torque = force x distance

## The Attempt at a Solution

Solution out of book is 142 kN

Attempts:

Mb = -(200kN)(2.5m) + (.895AE)(5) + 510

= 111 Kn

Mc = -(3m)(170kN) + (.895AE)(5)

= 114 kN

Md = (-80)(2.5) - (100kN)(7.5m) + (.895AE)(2.5)

= 424.60 kN

Solving for force at F and G, Fy = 80 kN and Gy = 130 kN

where did I go wrong?
