comment How can an an ant lift 50 times its own weight and pull 30 times its weight?
This is the relevant section from your link: But in the rest of the universe, the scaling is actually much slower. Body mass increases along three dimensions, but the strength of legs and arms, which is proportional to their cross-sectional area, increases along just two dimensions. If a man is a million times more massive than an ant, he will be only 1,000,000 to the two-thirds power stronger: about 10,000 times, allowing him to lift objects weighing up to a hundred pounds, not thousands.

Thanks a lot for your answering & also for the interesting link.But my question is but how can you say that strength is related to Area of cross section of the muscle? A Google search did not give me a satisfactory definition of 'Strength' & its relation to the muscle's cross sectional area is not mentioned anywhere. Can you clarify?

Thanks. Your answer made sense but how can you say that strength is related to Area of cross section of the muscle? A Google search did not give me a satisfactory definition of 'Strength' & its relation to the muscle's cross sectional area is not mentioned anywhere. Can you clarify?

@Manishearth I'd like referenced claims. By the way, how long will it take for the mod to migrate this question?

@Manishearth I'll post the same question on Skeptics.

comment Question involving Vectors and Forces
I got $Fcos\alpha=600$ - a relation between $F$ and $\alpha$ but how do I get a second relation involving $\beta$? Any suggestions? And thanks for answering :)

I've modified the image. It now looks closer to the picture in the text book.
