Physics 141 (Spring 2009): Problem Set #10 (due 4 May 2009) Chapter 10 : Questions: (3), 5, (7), 12, 13, 15, 18, (21), 22, (27). Problems: 53, 56, 63, (64), (65), 67, 69, (70 * ), (71), (78), 79, (81), 83, 87, 92, (95), (96), (98), 100, 101, 103 ** . Chapter 11 : Questions: 5, (7), 11. Problems: 66, (67), 72, 74 *** , 75, 76. Comments : * Compare the results here with the case, already done in class, where we ignored the internal rotational properties of the object on the track. ** Compare with Chapter 6, Problem 69, from Problem Set #6. *** Consider the case of inFnitely many blocks, each positioned as far as possible to

Unformatted text preview: the right. What is the shape of the resulting “curve” in space formed by the blocks? Remarkably, this sort of conFguration is completely stable, without any other support. This partly explains the stability of arches. However, note the unusual feature that the position of the Frst (bottom) block depends on how many blocks there are going to be — you cannot just begin to build the arch, and then decide later how high you wish to go....
