## Homework Statement

The jib crane is designed for a maximum capacity of 10kN, and its uniform I beam has a mass of 200kg.

a)Plot the magnitude R of the force on the pin A as a function of x through its operating range of x=0.2m to x=3.8m.

b)Determine the minimum value of R and the corresponding value of x

## The Attempt at a Solution

Totally stumped on this one. It'll be great if someone could point me in the right direction.

I didn't even think the force would vary with distance :S. Isn't it only the moment about the point that changes? How do I determine the change in force with distance?
