Chapter 11, Problem 24A
Three people stand with their backs against a wall. They are all agile and in good physical condition. Their task is to lean over and touch their toes without toppling over. Rank their chances for success from highest to lowest.
Expert Solution & Answer
To determine
To rank: The persons for the chances of their success from highest to lowest.
Answer to Problem 24A
C> A> B
Explanation of Solution
Introduction:
For humans to lean over, and remain steady without toppling, their body condition and then the center of gravity must remain stable.
C has longer toes as compared to the other 2 persons. Using longer toes, C can maintain a stable center of gravity. Either he is standing or if he leans over. A would have lesser chances than C as he is in perfectly good healthy condition. With a normal span of toes, his center of gravity might unbalance after a while. However, B will have the least chances of leaning over. Because B has an obese stomach that might fail B to lean over without toppling.
Conclusion: Thus, in terms of getting success in lean over without toppling is C > A> B
