Task id10789

Determine the pressure p1 that must be applied to the piston of the power cylinder (Fig.) to create a force along the rod P = 7850 N. The friction forces of the piston in the cylinder and the rod in the oil seal are equal to 10% of the total pressure on the piston. Excess pressure on the left side of the piston p2 = 9.81 N/cm2; D = 100 mm; d = 30 mm.
