Graphs problem 1

[tails009]

Hi there,

I have a problem in that I'm trying to create a graph that essentially creates a box. I have equations that gives me 2 results for pressures and 2 results for forces.

What I am trying to show is that Pp (5000psi) and Pi (-5000psi)only exist between FMAX (75000lbs) and FMIN (-75000lbs)

however I've been messing with mathcad for hours now and still haven't got it figured out. I've attached a Jpeg of what I am trying to achieve.

Thank you in advance for your help.

Define Pp and Pi such that they evaluate to zero at FMIN and FMAX, and 5000 an -5000 at the next index point above FMIN and below FMAX. Then make the limits of the x-axis FMIN and FMAX.

Any chance of posting a Mathcad worksheet
