Question

What is the main use of spring balance?

Answer 1

they are also common in science education as basic accelerators. They are used when the accuracy afforded by other types of scales can be sacrificed for simplicity, cheapness, and robustness. A spring balance measures the weight of an object by opposing the force of gravity acting with the force of an extended spring.

Answer 2

Answer:

Spring Balance is a device used for measuring the force acting on an object. It consists of coiled spring which gets stretched when a force is applied to it. Stretching of the spring is measured by a pointer moving on a graduated scale. The reading on the scale gives the magnitude of the force.
