Answer:
The additional weight and mass needed for lifting the other piston slowly is 2500 N and 254.92 kg, respectively.
Explanation:
By means of the Pascal's Principle, the hydraulic lift can be modelled by the following two equations:
Hydraulic Lift - Before change
Hydraulic Lift - After change
Where:
- Hydrostatic pressure, measured in pascals.
- Change in hydrostatic pressure, measured in pascals.
- Cross sectional area of the hydraulic lift, measured in square meters.
- Hydrostatic force, measured in newtons.
- Change in hydrostatic force, measured in newtons.
The additional weight is obtained after some algebraic handling and the replacing of all inputs:
Given that and
, the additional weight is:
The additional mass needed for the additional weight is:
Where:
- Additional weight, measured in newtons.
- Additional mass, measured in kilograms.
- Gravitational constant, measured in meters per square second.
If and
, then:
The additional weight and mass needed for lifting the other piston slowly is 2500 N and 254.92 kg, respectively.
