This produces the somewhat odd result that a correctly balanced Roberval balance, unlike a beam balance, can be "balanced" in any arm position: so long as the masses of the objects on both sides are equal or the pans are empty, it will balance with the right arm up and the left arm down, as well as the left up and the right down, as well as any ...
The balance (also balance scale, beam balance and laboratory balance) was the first mass measuring instrument invented. [1] In its traditional form, it consists of a pivoted horizontal lever with arms of equal length – the beam or tron – and a weighing pan [10] suspended from each arm (hence the plural name "scales " for a
The arm from which the object to be weighed (the load) is hung is short and is located close to the pivot point. The other arm is longer, is graduated and incorporates a counterweight which can be moved along the arm until the two arms are balanced about the pivot, at which time the weight of the load is indicated by the position of the ...
Pointers - The scale pointer marks the equal point of the object's mass on the scale and mass on the beam; Zero adjustment knob - This is used to manually adjust the triple beam balance to the 'zero' mark (check to ensure that the pointer is at zero before use). Before using triple beam balance, the scale pointer should be at zero.
