Take four springs, two of the same length and the remaining two of the same and radius. Make
arangements for measurement, a laboratory stand with clamp, a hanger, a metre scale and a
weight box with a set of varying weights.
Support the spring, one at a time vertically from the laboratory same. Add a musle weight at the
bottom of the honger. Measure the extent on the metre scale attached to the spring. Take 6-7
readings by gradually increasing the weight on the hanger.
In each spring, draw a graph between the load suspended from the hanger at the exterior of the
spring. Write your results in the form of a table and properly interpret them. This project has
application in spring balance.

Answer:
A spring scale or spring balance or newton meter is a type of weighing scale. It works by Hooke's Law, which states that the force needed to extend a spring is proportional to the distance that spring is extended from its rest position. Therefore, the scalemarkings on the spring balance are equally spaced.If the spring balance is hung from a fixed point, the necessary force is transmitted through the spring balance. When a stretching force of 10N is measured on a spring balance, the same stretching force is applied to opposite ends at the same time. The reading is 10N. A spring balance is lying on a table
A spring scale measures weight or force when an object is hung from its hook. ... This one has a dual scale that reads 0-1000 g in 10 g increments and 0-10 Newtons in 0.1 Newton increment.
It consists of spring fixed at one end with a hook to attach an object at the other. It works by Hooke's Law, which states that the force needed to extend a spring is proportional to the distance that spring is extended from its rest position. Therefore, the scale markings on the spring balance are equally spaced.
Results on the basis of above experiments.
Explanation:
It is a test to test the extension value of spring. A spring is a round mesh (thicker than wire)of a rod of small diameter and of large length. It is basically made up of stainless steel which make it practical to take too much load. Stainless steel ha good shear strength.
In gradual increasing weight, the springs having more cross-sectional area (large radius) are extended less due to resistance offered by the spring.
But, springs having more length as compared with above case are extended less due to more turns of metal.
In case of compression, the above cases have opposite results.
