One common method of measuring mass is to tare the scale and measure the mass directly. One simple design utilizes a rigid fibre as a horizontal beam, supported at its centre by a stretched horizontal quartz torsion fibre sealed to it at right angles. The amount of torsion necessary for restoration is read by means of a dial attached to the end of the torsion fibre. What does a balance sheet tell us? The principles on which ultramicrobalances have been successfully constructed include elasticity in structural elements, displacement in fluids, balancing by means of electrical and magnetic fields, and combinations of these. Torsion balance, device used to measure the gravitational acceleration at the Earth’s surface. For the best design, two or more additional knife-edges are located between the end bearing and the pan, one to prevent tilting of the plane and another to fix the centre of load at a particular point on the end knife-edge. The deflection of the beam caused by adding the sample to one pan is restored by rotating the end of the torsion fibre until the beam is again in its horizontal position and the full range of torsion in the suspending fibre can be applied to the measurement of the load added to one pan. A later improvement in design was the use of a pin through the centre of the beam for the central bearing, introduced by the Romans about the time of Christ. What does available balance and actual balance mean? The balance usually operates in a gas-tight chamber, and a change in weight is measured by the change in the net buoyant force on the balance due to the gas in which the balance is suspended, the pressure of the gas being adjustable and measured by a mercury manometer connected with the balance case. The most obvious method of using a balance is known as direct weighing. What Does the Balance Function Measure?
