## Homework Statement

Basically its all on the attached sheet as i don't know how to stick images in the post.

im having trouble finding two distances x and y (x+y= 100mm) just need a little help rearranging the equation on the attached word doc.

But ‘A’ passes through origin so c = 0.

m = 1/20 bar per mA

We know the values of Kc and A and hence can find x and y. Sorry but I can't fathom how to rearrange it as A=5cm^2 this multiplied by an unknown number in mm means it is tiny and hence once divided by the top figure will give a massive value for Po. When we know it is 0.05?

(N.B. be sure to have all measurements in S.I units.)

## Homework Equations

Po= (Kc*y)/A*x *Iin + (Fs*z)/A*x

A= 5cm^2

Z= 75mm

x+y = 100mm

Kc= 2500N A^-1

Po is in bar and is 0.2 at 4mA

Iin is mA and is 4 at 0.2Bar

## The Attempt at a Solution

i can't attach any files I am afraid as it won't work?

any help greatly appreciated
