A spring scale, spring balance or newton meter is a type of mechanical force gauge or weighing scale. It consists of a spring fixed at one end with a hook to attach an object at the other. [ 1 ] It works in accordance with Hooke's Law , which states that the force needed to extend or compress a spring by some distance scales linearly with ...
Before using triple beam balance, the scale pointer should be at zero. The zero adjustment knob can be used to adjust the scale pointer. The objects are placed on the pan and the riders are adjusted. The hundred rider should be initially adjusted and follow by the tens rider. The ones rider is adjusted until the scale pointer is at zero again.
