How can you tell which of three balls is the lightest or heaviest using a simple balance that consists of two pans?
Tough question to get into one sentence! You can do it in two weighings. Select any two of the balls and place one on each pan. If the scale balances, the third ball is the oddball. A second comparison will determine whether the oddball is lighter or heavier than the other two balls. Simply replace one of the first two balls with the oddball. If the oddball is heavier, its pan will drop; if it's lighter, its pan will rise. But what if the scale fails to balance the first time? (It is twice as likely that the scale will fail to balance when selecting two of the three balls at random for the first comparison!) If the scale fails to balance on the first comparison of two randomly selected balls, then you know that the oddball is on the scale, but you do NOT know which one it is, and you don't know whether it's heavier or lighter than the other two. A second comparison will resolve those issues. Remove the lighter ball from its pan and replace it with the third ball. If the scale remains out of balance, then you know that the heavier ball is the oddball, which is, of course, heavier than the other two. If, however, the scale balances, then the ball you removed is the oddball and is lighter than the other two.

Is beam balance a complex machine?
No, a beam balance is a simple machine. It consists of a beam supported at a balance point, with weights on each side used to determine the mass of an object by balancing the forces.
What is a lever balance?
A lever balance is a simple machine used to measure weights by comparing an unknown weight to a known weight. It consists of a bar that pivots on a fulcrum, with the two sides of the bar holding the weights. When the lever is balanced, the weights on each side are equal.
On which simple machine is the equal arm balance used?
The equal arm balance is used on a lever, in particular, the class 1 lever. It consists of a beam that pivots around a central point with two identical arms on either side for balancing weights on a fulcrum.
Balance scale inventor?
The balance scale was invented by the ancient Egyptians around 3000 BC. This simple device consists of a beam pivoted at its center with pans on both ends to hold the objects being weighed. It is still widely used today for measuring the weight of objects.
