Explain the principle of multiplication of thrust. |
|
Answer» Principle of multiplication of thrust by transmission of fluid pressure : The normal force exerted by a fluid on any surface in contact with it is called the thrust. Consider two hydraulically connected cylinders, one of cross section a and the other A, as in figure. If a force Fa is exerted on the smaller piston, pressure p = \(\frac{F_a}a\) s produced and transmitted undiminished throughout the liquid. Then, the thrust FA on the larger piston is FA = pA = \(\frac{A}a\)Fa If A = na, FA = nFa,i.e., the thrust on the larger piston is multiplied n times. This is known as the principle of multiplication of thrust by transmission of fluid pressure. |
