1.	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 ?
Answer» SOLUTION :Pressure on thepistondue 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.
