100: 175 800 200 The mechanism of Prob. 2/56 is repeated here. If a constant 750-N force is applied to the seat as shown, determine the pressure p which must act against the 30-mm-diameter piston in the hydrau- lic cylinder AB to establish equilibrium of the machine. Plot the required pressure p over the range -20° 0 ≤ 45° and assume no mechanical interference within this range of motion. What is the maximum pressure which the cylinder must develop for this range of motion? Note: Figures CDFE and EFGH are parallelograms.
