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?arrow_forwardDetermine the magnitude of the minimum force P needed to prevent the 20 kg uniform rod AB from sliding.
