Question

Hang in the balance experiment.. using a yard stick and a penny(standard weight)
1.) If the standard has a mass of 100-grams, estimate the largest amount of mass that could be measured. 2.) which modification would provide more precise results: a shorter arm with a heavier ball, or a longer arm with a lighter ball? And why?

Explanation / Answer

(1) It depend upon the length of the yardstick becasue moment produced by the mass about the hinge
balance the stick.
Hence if the length is 1 foot then it can meaure up to 500 gram.
(2) A longer arm with lighter ball will provide more precise result.
Because it increase the sensitivity of the device.
