Can anyone do help me do this?

We were asked to draw a gear puller (and I have already made one)

Now we are asked to do a (Stress/strain simulation of one of the jaws assuming a force of 1500N is required to remove a 40mm diameter gear from a 20mm diameter shaft, if both are made of steel and are shrink fit?)

P.S

I have played with jaw trying to do the simulation so I might have missed it up.
