Determine what effort F1 should be applied to the handle of the hydraulic press so that it compresses the body "K" by the force F2. The diameter of the pump piston d, the diameter of the press plunger D. Body and plunger weight is G. G. The length of the pump arm a, the length of the arm b. The friction of the piston of the pump and the plunger is neglected.
Given: F2 = 30,0 kN = 30 * 103H; G = 5000H = 5 * 103H; d = 0.014 m; D = 0.13 m; a = 0.53 m; b = 0.06 m.
