Main Question or Discussion Point

Hi Guys,
What would be the right formula to calculate this simple force.
Is it as simple as (950/150) * 1000 ?
See the attached sketch.
Thanks

I do not see any 150 in the sketch. If that is supposed to be 400, then, yes, the formula is correct.

Sorry,
Yeah 400 is right
Thanks
