A hydraulic automobile lift is designed ...

A hydraulic automobile lift is designed to lift cars with a maximum mass of `3000kg` . The area of cross - section of the piston carrying the load is `425cm^(2)` . What maximum pressure would the smaller piston have to bear ?

Text Solution

Verified by Experts

Pressure on the piston due to car ,
`thereforeP=(3000xx9.8)/(4.25xx10^(-2))`
`=6917xx10^(2)`
`=6.92xx10^(5)Nm^(-2)`
This is the maximum pressure that the smaller piston would have to bear.

For the system shown in the figure the cylinder on the left at L has a mass of 600 kg and a cross sectional area of 800cm^(2) the piston on the right at S has cross sectional area 25cm^(2) and negligible weight if the apparatus is filled with oil (rho=0.75gm//cm^(3)) find thhe force F required to hold the system in equilibrium.

A vertical cylinder of cross-sectional area 0.1m^(2) closed at both ends is fitted with a frictionless piston of mass M dividing the cylinder into two parts. Each part contains one mole of an ideal gas in equilibrium at 300K . The volume of the upper part is 0.1m^(3) and that of lower part is 0.05m^(3) .What force must be applied to the piston so that the volumes of the two parts remain unchanged when the temperature is increased to 500K ?

A magnetic field of 100 G (1 G = 10^(-4) T) is required which is uniform in a region of linear dimension about 10 cm and area of cross-section about 10^(-3) m^2 . The maximum current-carrying capacity of a given coil of wire is 15 A and the number of turns per unit length that can be wound round a core is at most 1000 turns m^(-1) . Suggest some appropriate design particulars of a solenoid for the required purpose. Assume the core is not ferromagnetic.

In a car lift compressed air exerts a force F_(1) on a small piston having a radius of 5.0 cm . This pressure is transmitted to a second piston of radius 15 cm . (See figure).If the mass of the car to be lifted is 1350kg .Calculate F_(1) . What is the pressure necessary to accomplish this task ? (g=9.8ms^(-2))

As shown , a piston chamber pf cross section area A is filled with ideal gas. A sealed piston of mass m is right at the middle height of the cylinder at equilibrium. The friction force between the chamber wall and the piston can be ignored . The mass of the rest of the chamber is M .The atmosphere pressure is P_(0) . Now slowly pull the piston upwards , find the maximum value of M such that the chamber can be lifted off the ground. The temperature remains unchanged.

An ideal gas enclosed in a cylindrical container supports a freely moving piston of mass M . The piston and the cylinder have equal cross-sectional area A . When the piston is in equilibrium, the volume of the gas is V_(0) and its pressure is P_(0) . The piston is slightly displaced from the equilibrium position and released. Assuming that the system is completely isolated from its surrounding, the piston executes a simple harmonic motion with frequency
