Beam Balance
BEAM BALANCE
Aim: To calculate the density of a regular shaped object using a beam balance.
Apparatus: Physical beam balance, vernier calliper, weight box & a given object,
Theory: Density is important and characteristic property of matter. Density is the measure of the compactness of a body. After making independent measurements of mass and volume, Density is calculated by the mass per unit volume of a substance.
Density = Mass
Volume
Where Volume = l x b x h
l = length of the block
b = breadth of the block
h = height of the block
Procedure: To find the dimensions, l, b, h, of the object; we use a vernier calliper. Record zero error, if any. Place the block on one of the plates on the beam
