What is spring balance for Class 8?

What is spring balance for Class 8?

Answers. Spring balance is a device used to measure the weight of small bodies. I t consisits of a spring to hang the weights. As the weigths are hung to the spring it stretches the the pointer indicates the weight hung or the force applied on the spring.

What are the two types of spring balance?

Two types of balances, the beam balance and the spring balance are commonly used for measuring weight in shops.

What is the difference between common balance and spring balance?

Both beam balance and spring balance are commonly used for measuring weights in shops. The beam balance actually measures the mass whereas the spring balance measures the weight. The force produced by a load is the weight. So, the displacement produced by the weight is used to find the weight of the object.

How can we use spring balance to measure the weight of an object?

Answer: Measure weight or force by hanging objects from the spring scale hook. Measure weight or force by hanging objects from the spring scale hook. Measure loose material, such as sand, by pouring it into a plastic bag and hanging the bag from the hook.

What is spring balance and its uses?

Spring balances provide a method of mass measurement that is both simple and cheap. The mass is hung on the end of a spring and the deflection of the spring due to the downwards gravitational force on the mass is measured against a scale.

What is spring balance?

spring balance, weighing device that utilizes the relation between the applied load and the deformation of a spring. This relationship is usually linear; i.e., if the load is doubled, the deformation is doubled.

What is the principle of spring balance?

Hooke’s law
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.

Who invented spring balance?

Christiaan Huygens
Drawing of one of his first balance springs, attached to a balance wheel, by Christiaan Huygens, inventor of the balance spring, published in his letter in the Journal des Sçavants of 25 February 1675.

What are the structural differences between a spring scale and a balance scale?

A spring scale measures distance that the object is displaced, whereas a beam scale balances the object against another mass. Both measure the mass of an object, although this is commonly referred to as the weight of an object.

What is spring balance on what principle does it work?

How does a spring balance work explain with help of an activity?

A spring balance measures the weight of an object by opposing the force of gravity acting with the force of an extending spring. 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.

Does spring balance measure pressure?

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

What is an springspring balance?

Spring balances provide a method of mass measurement that is both simple and cheap. The mass is hung on the end of a spring and the deflection of the spring due to the downwards gravitational force on the mass is measured against a scale.

How do springspring scales work?

Spring scales are used in many settings where people need to quickly weigh things, and pinpoint accuracy is not necessarily needed. Several companies sell portable spring scales with hooks which can be tremendously useful. To use such a scale, the scale is hung from a fixed object, and the object being weighed is attached to the hook.

How do you use a spring balance to measure pressure?

Attach the spring balance to the brush-spring arm. 3. While pulling lightly on the paper, raise the spring balance perpendicular to the brush until the paper begins to slip free. 4. Read the pressure at this point. 5. Take two or three readings and average the values. Divide the reading by the contact area of the brush.

How do I adjust the spring balance on my Electric Brush?

1. Raise the brush and insert a piece of paper between the brush and the commutator. 2. Attach the spring balance to the brush-spring arm. 3. While pulling lightly on the paper, raise the spring balance perpendicular to the brush until the paper begins to slip free. 4. 5. Take two or three readings and average the values.
