Problem of the Week

for Tuesday, April 16, 2013

Mr. Bailey designs a perfectly balanced mobile. He cuts pieces of silver wire of identical length and thickness and bends them into squares, equilateral triangles, and circles and hangs them as shown below. Mr. Bossy makes figures of the same size, shape and arrangement as Mr. Bailey, but instead of making them with silver wire, he cuts them from sheet metal. How does Mr. Bossy's mobile hang?
