Apply Lami's theorem on sling shot and calculate the tension in each string? |
Answer» SOLUTION : Given F = 50 N, `theta = 30^@` Here T is resolved into its components as T SIN `theta` and T cos `theta`as shown. ACCORDING to Lami.s THEOREM, ` (F)/(sin 2 theta) = (T)/(sin (180 - theta)) = (T)/(sin ( 180 - theta))` `(F)/(sin 2 theta) = (T)/(sin theta)` `(F)/(2 sin theta cos theta) = (T)/(sin theta)` ` therefore T = (F)/(2 cos theta) = (50)/(2 cos 30^@) = 28.868 N ` |
