What's a beam balance?
Similarly one may ask, what is a beam balance?
The beam balance is a device used for the determination of the mass of a body under gravitation. It consists of a beam supported at the centre by an agate knife edge resting on a support moving inside a vertical pillar. The beam carries a light pointer which moves over a scale.
Beside above, is beam balance a simple machine? Lever is a type of simple machine that is used to lift the heavy loads. It is made of a rigid bar that moves about a fixed point called fulcrum. It consists of three parts, effort arm, fulcrum and load arm. Beam balance, scissors, crowbar, etc are some examples of the first class lever.
Likewise, people ask, how does a beam balance work?
A beam balance works on the principle of moments. According to the principle of moments at equilibrium, the anti-clockwise moment due to the weight of an object on left pan of the beam is equal to the clockwise moment due to the standard weights on the right pan of the beam.
What are the uses of beam balance?
The triple beam balance is used to measure masses very precisely; the reading error is 0.05 gram. With the pan empty, move the three sliders on the three beams to their leftmost positions, so that the balance reads zero.
