Concept explainers
Propose a force standard different from the example of a stretched spring discussed in the text. Your standard must be capable of producing the sane force repeatedly.

To propose: a standard force that is different from the example of a stretched spring.
Explanation of Solution
Introduction:
The force acting on a stretched string can be calculated by calculating the stretch produced in the string. Here, we need to propose a force standard which is different than this stretched spring.
The above figure shows the arrangement of Pascal’s law. When a force is applied on the beaker A, the water level of beaker B rises by a height h .
The pressure acting on the Beaker is given as
So,
V is the volume of liquid raised in the beaker B. So by using this standard, we can measure the forces acting on beaker A.
