Your foot is on one end, but what is holding the other end of the scale?
So each one of my calf muscles easily lifts much more than 31 kilograms (because that's not counting the weight of my own body).
hen I tried to see if I could still stand on my tip-toes despite carrying all that extra weight around.I could. Without much trouble, either.
Did you lift with effort ?
Without much trouble
Essentially, the claim that your leg will only deliver 17 KgF is impossible. You just aren't measuring it properly.
This is an accurate test
If you remain on tiptoe this temporary force will decrease to zero.
Can a human lift his body with force less than his weight ?
This is an experiment which shows that a human can lift his body with force smaller than lifting any other equivalent mass.
As this is class 3 lever and both my weight and the force of the calves and feet I lift my body with are at the heel, the force I need to lift my body with must be greater than my weight " greater than 60 kg" However in fact I lift my body with those smaller x kilograms
The force to lift a mass must always be greater than weight " my case is an exception"
A massive human can stand on weak toes
