The area of cross-section of the wider tube shown in figure is $800 {\mathrm{cm}}^2$^​. If a mass of $12 \mathrm{kg}$ is placed on the massless piston, the difference in heights h in the level of water in the two tubes is

For the system shown in the figure, the cylinder on the left at$L$has a mass of $600 \mathrm{kg}$ and cross-sectional area of $800 {\mathrm{cm}}^2$. The piston on the right, at $S$, has cross-sectional area $25 {\mathrm{cm}}^2$ and negligible weight. If the apparatus is filled with oil$\left(\rho =0.75\mathrm{gm} {\mathrm{cm}}^{-3}\right)$. Find the force $F$required to hold the system in equilibrium

A force of $500 \mathrm{N}$ is executed on a hydraulic piston of cross sectional area of $100 {\mathrm{cm}}^2$. The cross-sectional area of other piston which supports a truck of a tonne weight is [use $g=9.8 \mathrm{m} {\mathrm{s}}^{-2}$]

The working of hydraulic lift is based on the principle of

A car hoist is operated by a hydraulic as pictured. Determine compressive force $F$ applied by hydraulic to keep the car-weight $W$ in equilibrium at given position.

A hydraulic lift is designed to lift heavy objects of maximum mass $2000 \mathrm{kg}$. The area of cross section of piston carrying the load is$2.25\times {10}^{-2}{\mathrm{m}}^2$ What is the maximum pressure the piston would have to bear?

The mechanical advantage of hydraulic lift is always equal to one.

In a hydraulic lift, the small piston has an area of $2 {\mathrm{cm}}^2$ and the large piston has an area of $80 {\mathrm{cm}}^2$. What is the mechanical advantage of the hydraulic lift?

Find the mechanical advantage of the hydraulic lift.

Mechanical advantage of a hydraulic lift is directly proportional to the:

In a hydraulic lift, the mechanical advantage is defined as the ratio of the area of cross-section of the piston of output force to the area of cross-section of the piston of the input force. The force on the piston of the smaller area of cross-section is more than that on the piston of the larger area of cross-section.

In a car lift, the mechanical advantage is $2.5$. If the mass of the car to be lifted by the larger piston is $1200 \mathrm{kg}$, calculate the force exerted by the compressed air on the smaller piston. Take  $g=10 \mathrm{m} {\mathrm{s}}^{-2}$.
