Question

Quizplus · Accepted Answer

When an athlete is scaled up in size, their muscle strength increases by the square of the scaling factor, but their body weight increases by the cube of the scaling factor. This means their relative strength compared to their body weight decreases, making it harder for them to perform the same number of pushups.
