Define one pascal (Pa), the S.I. unit of pressure.
Explain the working of a hydraulic brake with a simple labelled diagram.
What should be the ratio of area of cross section of the master cylinder and wheel cylinder of a hydraulic brake so that a force of 15 N can be obtained at each of its brake shoe by exerting a force of 0.5 N on the pedal ?
A force of 50 kgf is applied to the smaller piston of a hydraulic machine. Neglecting friction, find the force exerted on the large piston, if the diameters of the pistons are 5 cm and 25 cm respectively.
66640 Pa pressure is exerted by 0.50 m vertical column of a liquid. If g = 9.8 Nkg−1, calculate the density of the liquid.
The area of cross-sections of the pump plunger and press plunger of a hydraulic press is 0.02 m2 and 8 m2 respectively. If the hydraulic press overcomes a load of 800 kgf, calculate the force acting on the pump plunger.
