For a man, it is very easy to lift a girl who weighs 50-60 kg.
👧But for the same man, it is difficult to lift a 15kg gas cylinder.
👧Most people think that it is the interest that matters when doing work.
👧But that is a bull shift when we are concerned about lifting jobs, because there a lot more physics involved than interest.
👧So when you lift a girl you use all your back, arm muscle, and leg muscles. And the area of contact also makes a great contribution to that lifting job.
👧But when you lift a cylinder you use only arm muscles and the area of contact with the cylinder is so less. So there you feel more burden.
👧It will be easier to lift a cylinder like the way you lift a girl.
👧It will be difficult to lift a girl like the way you lift a cylinder.
👧So when people say this to you, explain to them the physics behind it.
