tiese r answer in two different ways ss you ove to determine the 2) the number of clothespins ee of crayons thespins th at will balance one ng in each case. s if the crayons from the box had ring? Explain in Chicago. Each has an equal arm balance at home 1. In a phone conversation they discover that ng at school. ame, but not from the same company. They want to er mass. How can they do this by using their equal arm her? uare nut on each of the beams shown below in order to 000O000Oo000o0000 0o0 oo00oogg000 00000o000000000000

Explanation / Answer

We need to find torque developed by each hanging nut (assume unit weight- m). Assume unit distance between circles as "d"

So we have one nut at distance "d", another nut at distance "6d"; while two nuts at other distance at "2d". We will denote acceleration due to gravity force "g"

So, torque developed at middle(positon of beam) by these 3 hanging nut weight is:

(m*g)*d + m*g * 6d - (2m*g) * (2d)  

= 3 * m*g*d

To produce this counter torque , Another nut (of mass "m") must be hanged at left side of beam at distance "3d".
