Now move the 10 gm rider from notch to notch in a similar manner as you did with the 100 gm notch until the pointer drops below zero at which point, you must move it back a notch. This is the maximum weight that the triple beam balance can measure. When all three riders are positioned completely to the right, their combined weight equals 500 gm + 100 gm + 10 gm = 600 gm. The third beam, located at the back, has 100 gm scale with a 10 gm rider. The second beam which is located in the middle, has a 500 gm scale with 100 gm rider on it. When positioned such that the pan is on the left hand side and the scale and pointer to the right, the beam which is located on the front has a 10 gm scale and a 0.1 gm rider on it. Each of these three beams has a weighted rider on it, which the user can slide along the length of the beam to determine the object’s mass. Triple Beams and RidersĪs the name of this apparatus implies, the triple beam balance comprises three beams which are individually used to determine the mass of an object. Together the pointer and the scale are used to ascertain when the beams are at their resting position and when the correct mass of an object has been found. By default, it points to zero on a labeled scale. The pointer is present on the right hand side of the triple beam balance. It can be turned to attain greater accuracy while measuring the weight of an object using the triple beam balance. The adjustment knob is present on the left hand side of the apparatus, beneath the pan. Therefore, it is primarily used as a laboratory apparatus. It can provide higher accuracy than a spring-based measuring scale, and has an error margin of only 0.05 gm. The triple beam balance is one such weighing device, which allows the user to accurately gauge the mass of an object in grams. For this, several different weighing devices have been developed over the years. Many chemical reactions depend upon precise measurement of the weights of the ingredients, without which they simply wouldn’t work. In science, especially in the fields of physics and chemistry, accurate measurements is a very important criterion for study and experimentation. It is therefore capable of giving the same mass reading on the Moon as it would on Earth, even though the Moon’s gravity is only 1/6th that of the Earth’s. Unlike the traditional spring balance which measures weight, the triple beam balance doesn’t rely on gravitational force. A triple beam balance measures the mass and not the weight of an object. ![]()
