- Left rope = T1 Right rope = T2 1/6 of 3.9 m = 0.65 m 3.9/2= 1.95 1.95 - 0.65 = 1.3 m from right rope. Take g = 10m/s^2 T1 = ((219 x 3.9)/2) + (744 x 1.3) = 1394.25 1394.25 = 3.9 x T1 1394.25/3.9 = T1 = 357.5 N (answer for left rope) T2 = ((219 x 3.9)/2) + (744 x (3.9 -1.3)) = 2361.45 2361.45 = 3.9 x T2 2361.45/3.9 = T2 = 605.5 N (answer for right rope)s

- the HOW is that if he moves 1/6 of the way to an end, then he's 1/3 of the way from that end and 2/3 of the way from the other end. The tension from the platform doesn't change, but the tension from the man on either rope is inversely proportional to his distance from either end; in other words, he's 1/3 of the way from the right end, so 2/3 of his mass goes to tension on that rope; he's 2/3 from the other end so 1/3 of his mass goes to tension on the left rope. the rest is just math!s
