The answer to last week’s lateral thinking challenge is. Q: A man lives on the twelfth floor of an apartment building. Every morning he takes the elevator down to the lobby and leaves the building. In the evening, he gets into the elevator, and, if there is someone else in the elevator — or if it was raining that day — he goes back to his floor directly. Otherwise, he goes to the tenth floor and walks up two flights of stairs to his apartment.

A: The man is a “little person”. He can’t reach the upper elevator buttons, but he can ask people to push them for him, or he can use his umbrella to reach it if it’s raining and he has it on his person.

This week’s lateral thinking challenge is.

Q: Manhole covers for sewer drains are typically circular in shape (the ones that are removable anyway). This shape has an important advantage over a square or rectangular shape. What is it?  

Another lateral challenge will appear next week along with the answer to this one.

    Hi again!

    1- It is easier to make a circular hole. Using a square or rectangular cover require that one re-shape the hole to fit the shape.

    2- When pressured, a circular hole is better at spreading the pressure on all sides of the circumference. Square or rectangular covers would have the pressure mostly affecting the edge closer to the point of the pressure.

    3- It can be easily flipped open from any point on the circumference.
