Question

The machine below forms metal plates through the application of force.  Two toggles (ABC and 
DEF) transfer forces from the central hydraulic cylinder (H) to the plates that will be formed.  The 
toggles then push bar G to the right, which then presses a plate (p) into the cavity, thus shaping 
it.  In this case, the plate becomes a section of a sphere.  If the hydraulic cylinder can produce a 
maximum force of F = 10 kN, then what is the maximum P value (i.e. Pmax) that can be applied to 
the plate when θ = 35°?  Also, what are the compressive forces in the toggle rods in that situation?  
Finally, what happens to Pmax and the forces in the rods as θ decreases in magnitude?
