Question 7: What is the principle of spring balance? Answer: The spring gets stretched due to the force exerted on it, this stretching produced is directly proportional to the stretching force. Question 8: State two precautions while measuring the volume in the cylinder. Answer: The measuring cylinder should be placed on a plain flat surface.

Spring balance is a force measuring device which works on the principle of Hooke's law. According to Hook's law, the force acting on the spring (along the axis of the spring) is directly proportional to the displacement of the spring, in the direction of the force. Construction of Spring Balance. Spring balance is made up of a coiled spring.

In an ideal spring, the spring force is proportional to its ends' displacement (x) from the equilibrium position. So, according to Hooke's Law, F s = -kx. Where F s is the spring force, x is the displacement from the equilibrium position, and k is the spring constant. The spring constant is the characteristic property of the spring.

The Spring Constant. The spring constant determines exactly how much force will be required to deform a spring. The standard international (SI) unit of measurement for spring constants is Newtons/meter, but in North America they are often measured in pounds/inch. A higher spring constant means a stiffer spring, and vice-versa.
