A hydraulic automobile lift is designed to lift vehicles of mass 5000 kg . The area of cross section of the cylinder carrying load is 250 cm 2 . The maximum pressure the smaller piston would have to bear is [Assume g = 10 m s - 2 ]
Options
- A20 × 10 6   Pa
- B2 × 10 5   Pa
- C200 × 10 6   Pa
- D2 × 10 6   Pa
Correct answer
D. 2 × 10 6   Pa
Step-by-step solution
The given data is m = 5000   kg g = 10   m   s - 2 A = 250 × 10 - 4   m 2 Using the formula of pressure, P = F A = m g A = 5000 × 10 250 × 10 - 4 = 2 × 10 6   N   m - 2 = 2 × 10 6   Pa
