Discussion Overview

The discussion revolves around the question of whether the weight of a person wearing shoes can be less than the sum of their body weight without shoes and the weight of the shoes. Participants explore potential reasons for observed discrepancies in weight measurements.

Discussion Character

  • Debate/contested

Main Points Raised

  • One participant claims to have found that their weight with shoes is greater than the sum of their body weight without shoes and the weight of the shoes.
  • Another participant suggests that measurement errors from the scale could explain discrepancies, noting that scales may have different accuracy levels depending on the weight being measured.
  • A participant proposes that the sponge material in a weighing machine might affect the readings, questioning if it could lead to a situation where the weight with shoes is less than the expected sum.
  • One participant expresses skepticism about the influence of sponge material on weight measurements.

Areas of Agreement / Disagreement

Participants do not reach a consensus; multiple competing views remain regarding the accuracy of weight measurements and the factors influencing them.

Contextual Notes

Limitations include potential measurement errors from scales, dependence on the type of weighing machine, and the influence of different materials on weight readings.

I Found that my body weight with shoes is found less than the sum of ( body weight without shoes + weight of shoes ).

example : Weight of body is A and Weight of shoes is B
Human weight wearing shoes is C

I Found that C > ( A + B ).

Is it possible ?

I don't believe so. It's probably a result of your scale having different weighing errors at different amounts of weight. IE if you put 5 pounds on it, it may be accurate to within 1-2 pounds, and if you put 150 pounds it may be accurate to within 2-3 pounds. If you put 155 pounds it may still be accurate to within 2-3 pounds. So if you add the first two measurements you could be off by several pounds compared to the third measurement just due to the errors inherent to the scale and the fact that you took multiple measurements.

Try doing several different measurements. Try putting your shoes on the scale and then pressing down and letting the scale come back up afterwards and see if that changes the measurement. Sometimes if it approaches the weight from the other way it will be different. Does that make sense?
 
Thanks for your answer which gives a possibility for these kind of situations as well.

I have seen the reverse as well in a new weighing machine where C < ( A + B ) does the sponge material available in it makes the difference ?

I think it's unlikely.
