How do you calculate the weight of two unknown masses using a class 1 lever?

We need to perform a condition of balance along a rod in which we can measure distances. Finally, find the weight ratio and measure the weight of one of the masses in order to find the weight of the second.

Explanation:

We need to see this problem using a sketch with a class 1 lever. And some numerical values to understand and how to make the proper calculations.

Let's say that we have a body in the form of a beam 1 meter long, then we put the two masses in each of the ends of the beam under the beam, we place the fulcrum and move up to the beam to obtain a horizontal position when horizontal position is reached the beam will be in balance.

Then we perform a sum of moments around the pivot point or fulcrum since we know the distances, we can find the mass relation in the condition of balance. For this example the ratio corresponds to M1 is 2.33 times heavier than M2.

explanation: in any substance/object, the particles inside it (atoms/molecules) constantly move in random directions and with random speeds (this motion is called brownian motion). as a result, the particles have some kinetic energy (which is proportional to the temperature of the substance).
