My Notes Ask Your Teacher A block of mass m 3 5.6 kg is pulled up a e 3 22 ncline as in the figure below with a force of magnitude F 36 N l002 PM 1/30/2017

Explanation / Answer

F = 170.6 N on the portion of the cable pointing downward.

vertical components of other 2 cables:
(T1)sin60° + (T2)sin30° = 170.6 N
[sqrt(3)/2](T1) + (1/2)(T2) = 170.6N
(T1)sqrt(3) + T2 = 256 [1]

horizontal components:
(T1)cos60° = (T2)cos30°
(1/2)(T1) - (T2)[sqrt(3)/2] = 0
T1 - (T2)sqrt(3) = 0 [2]

[1] - sqrt(3)[2]:
(T2)[1 + 3] = 256
T2 = 64 N

T1 = (64)sqrt(3)
T1 = 111 N
