Ratio of masses, individual weight calculations(Division B)

Post by Robot2020 » February 16th, 2020, 3:33 pm

Hi
I am a newbie at this event. For the division B, we need to find the ratio of the masses which means
Hang 2 masses A, B at a time. At equilibrium, by the law of moment, we can find the Mass A/Mass B ratio.
Similarly, for Mass Band Mass C and Mass B/Mass C ratio.
But how do we find the weights of the individual masses? They say they will give one known mass. So to find the mass A, mass B, mass C should we balance it separately to get the individual weights A, B,C.
Any help is appreciated.
Thanks!

You don't. Rules say you find ratios, not actual masses.

Thank you so much. How about the data graphs? What should be on the x axis and the y axis?

Thanks
