Beam Balance and Sensibility Concepts

The video tutorial explains the use of a beam balance, a weighing instrument for measuring gravitational mass. It covers the principle of moments, mathematical equations for mass calculation, and the concept of sensibility. The tutorial outlines the materials required and provides a detailed procedure for determining the sensibility and measuring the gravitational mass of an object. It concludes with the applications of beam balances in precision measurements, commonly used by goldsmiths and researchers.

What principle does a beam balance use to measure mass?

• Principle of relativity

• Principle of inertia

• Principle of moment

• Principle of buoyancy

In the formula m = W + (R - R0) * s, what does 'W' represent?

• Mass in the pan

• Weight of the object

• Sensibility of the balance

• Weight of the beam

What is the sensibility of a beam balance?

• The weight required to balance the beam

• The weight required to move the pointer to zero

• The weight required to calibrate the balance

• The weight required to shift the resting point by one division

Which material is NOT required for the sensibility experiment?

• Box of weights

• Spring scale

• Beam balance

• Rectangular wooden block

How are the turning points used in the procedure to find sensibility?

• To calibrate the weights

• To balance the beam

• To determine the zero resting point

• To calculate the mass of the object

What is the first step in finding the gravitational mass of an object?

• Place the object in the right pan

• Place the object in the left pan

• Calibrate the beam balance

• Calculate the zero resting point

What should be done if the pointer rests near the pan with less weight?

• Add weight to the pan with more weight

• Remove weight from the pan with less weight

• Add or remove weight to achieve equal oscillations

• Calibrate the balance again

What is the final step in calculating the gravitational mass of an object?

• Calculate the zero resting point

• Add all the weights in the right pan

• Balance the beam

• Determine the sensibility
