EXAMPLE 6-6 A pump delivers oil at a rate of
18.2gpm
into the blank end of the 3 -in-diameter hydraulic cylinder shown in Figure 6-17. The piston contains a 1-in-diameter cushion plunger that is 0.75 in long, and therefore the piston decelerates over a distance of 0.75 in at the end of its extension stroke. The cylinder drives a 1500-lb weight, which slides on a flat horizontal surface having a coefficient of friction (CF) equal to 0.12 . The pressure relief valve setting equals 750 psi. Therefore, the maximum pressure
(p_(1))
at the blank end of the cylinder equals 750 psi while the cushion is decelerating the piston. Find the maximum pressure
(p_(2))
developed by the cushion. Answer this according to si unit
