Name:_____________________ Partners: __________________________ 1 Cooperative Problems Week 13: Static Equilibrium 1. [YF 11.74] If you put a uniform block at the edge of a table, the center of the block must be over the table for the block not to fall off. If you stack two identical blocks at the table edge, the center of the top block must be over the bottom block, and the center of gravity of the two blocks together must be over the table. (A) In terms of the length L of each block, what is the maximum overhang possible with two blocks? Make a prediction, then test it using the blocks supplied by your TA. (B) Repeat part (A) for three identical blocks. (C) Repeat part (A) for four identical blocks.
