## Homework Equations

Sum of clockwise moment=sum of anticlockwise moment

## The Attempt at a Solution

I had drawn out the force diagram and listed out the information required.

The question asks me to find force acting by the support B.

I troubled myself by taking moments about A and multiplying every forces with their respective distances from A.

However the answer was simple, they just added all other forces together, 33 + 4.4 + 129 = 166N.

I can't figure out where is the pivot. Or is there even a pivot? What's the theory behind this calculation?
