Answer:

A beam balance is used to measure the mass. It consists of a horizontal beam, supported at its centre. The beam can move freely about its support and a pointer is attached to the centre of the beam.

Answer 2

Answer:

The physical balance consists of a light and rigid beam of brass, a metallic pillar, a wooden base, two pans, a metallic pointer, and an ivory scale. The plumb-line indicates whether the balance is horizontal. In an ideal condition, the plumb-line is aligned with the end of the knob fixed to the pillar.
