Not illustrated. 1902 Excerpt: ...the velocity of the wheel will increase uniformly from zero to N turns per second. The average velocity of the weight is then--0 ] V _ V And as distance moved over = average velocity x time--V li=x t 2 2/1 therefore V =--feet per second Similarly, the number of turns (//) made by wheel while the weight is falling is--- =-X / 2 2n therefore N =--turns per second To determine n, put a 7-lb. weight on the cord to strain it straight, and turn the wheel by hand to see as near as possible how many turns the wheel makes in falling a certain number of feet (the number of feet is the distance through which the weight is going to be permitted to fall in the experiment). Call the distance // feet, and the number of turns (//). The body must be made to fall through h feet during every experiment. Now determine with the stop-watch how long it takes the weight 7 lbs. to fall h feet while turning the flywheel, repeating the observation three times, and determine the average time. Tabulate thus--Width of rim 2-1 ins. Radial thickness 1-36, Outside diameter 23-85 Inside 21-13 - Mean diameter of spoke... 0-9 Length i0-6 Number of spokes 6 Calculated weight of rim... 54-5 lbs. spokes... 10-9 hub... 2-0 whole wheel. 67-4 It was found in the experiment that a weight of 1 lb. just balanced the friction of the wheel. As the weight of the wheel was 67-4 lbs., the friction with 7 lbs. on hub = 1 08 And with 14 and 21 lbs. it is i-i9 and i-2Q lbs. respectively. Substitute the numerical values in the equation--Energy A = Energy B + Energy C + Energy D and find the error in each case; that is, the excess or deficit of the right-hand side of the equation over the left. Then tabulate thus--Result of Flywh...
