SUMMARY
The perception of weight when lifting a gas cylinder compared to a child of the same weight is influenced by several factors, including the distribution of weight and surface area. A 14 kg gas cylinder feels heavier than a 14 kg child due to the cylinder's compact shape and the pressure exerted on the lifter's hands. The discussion also highlights the concept of weight distribution, as illustrated by the circus example where an elephant can stand on a plank supported by a performer without causing injury. This suggests that the perceived weight can be affected by how weight is distributed across a surface.
