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 block, mass, volume, density, beam, balance, vernier, calliper, zero, weight, vsr, vsd, total, reading, object, no msr, msr, mean, lc, height, error, tr, corrected, cm, breadth, weights, using, sure, scale, record, pointer, mg, measurements
