Question

Draw a well labeled diagram of a spring balance. Discuss about its working in detail with respect to magnitude of force.

Answer 1

Answer:

Spring balance is used for measuring : (1) The force acting on an object (2) The force of friction (3) Magnitude of the pressure (4) Relative motion between the object

Spring balance is used to determine the force acting on the object (weight). Spring balance works on the principle of Hooke’s law.

Hooke’s law states that the strain of the material is proportional to the applied stress within the elastic limit of that material.

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. A spring scale cannot measure mass, only weight.

A spring balance can be calibrated for the accurate measurement of mass in the location in which they are used, but many spring balances are marked right on their face "Not Legal for Trade" or words of similar import due to the approximate nature of the theory used to mark the scale. Also, the spring in the scale can permanently stretch with repeated use.

A spring scale will only read correctly in a frame of reference where the acceleration in the spring axis is constant (such as on earth, where the acceleration is due to gravity). This can be shown by taking a spring scale into an elevator, where the weight measured will change as the elevator moves up and down changing velocities.

If two or more spring balances are hung one below the other in series, each of the scales will read approximately the same, the full weight of the body hung on the lower scale. The scale on top would read slightly heavier due to also supporting the weight of the lower scale itself.

Answer 2

Answer:

The force acting on an object is measured using a spring balance. A pointer that moves along the graded scale indicates how far the spring has stretched. The force's magnitude is indicated by the reading on the scale.

Working of spring balance-

• A spring balance is a mechanical tool that measures an object's weight or force by working against gravity using the force of an extended spring.
• Its functioning is based on the Hooke's law premise. Hooke's rule A spring's elongation is inversely related to the load it can support. As a result, the spring's scale markings are evenly spaced where F=k.x.

F=load attach

F=load attach k=spring constant

F=load attach k=spring constant x = spring elongation

• If the weight hanging on it doubled, the deformation of the spring and the load attach would also double.
• Steel pins are inside the spring, and its top end is attached to the support so that the lower end hooks can hold objects.
• So, the force exerting on the object is measured using a spring balance.
• A spring balance is used to determine the object's weight. The spring extends when a load is hung on it, and the extension of the spring is proportional to the weight of the load.
