41. (a) Referring to Sample Problem 15-5, we see that the distance between P and C is hLLL =−= 2 3 1 2 1 6 . The parallel axis theorem (see Eq. 15–30) leads to = 1 12 += 1 12 + 1 36 = 1 9 . 22 2 2 Im L m h m Lm L F H I K Eq. 15-29 then gives T I mgh L gL L g == = 9 6 2 2 3 2 ππ π / / which yields T = 1.64 s for L = 1.00 m. (b) We note that this T is identical to that computed in Sample Problem 15-5. As far as
