## Homework Statement

I'm to design a crane, and therefore I need to find the reactions in the jib and also make the crane stable.

1. I need to find the max. load that the crane is able to lift. Therefore i have to find the reactions where the horisontal and vertical boom is meeting.

2. I need to find out the moment in the bottom of the vertical beam in order to make the crane stable. Now i should have the max weight, and therefore the weight of the stone. And it should be easier to calculate

## Homework Equations

## The Attempt at a Solution

The sum of all the forces needs to be 0. F=0

The angle is 90 degrees, so that is not going to be a problem

The wire from the horisontal beam is only ½ m.

But since i don't know the weight of the stone, I don't know where to begin?
