Hello pls write this on white page ASAP just copy this whole on white page I'll UPVOTE
Write the forces in vector form,
F = 55 i
F = F; (- sin a î + cos a j)
F = 130 (- sin 65° î + cos 65° j)
F =-117. 82 î + 54. 94 j
F = Fs (- cos e î + sin e j)
F = 55 x (- cos 54. 211° i + sin 54. 211°)
F = 32. 164 i + 44. 614 j
Step 3
The resultant force is,
F =F +F +F
F = 55 i - 117. 82 î + 54. 94 j + 32. 164 î + 44. 614 ĵ
F = -30. 656 î + 99. 554
Calculate the magnitude of the resultant force,
F= V(-30. 656)2 + (99. 554)²
F = 104. 167 Ib,
The direction of the resultant force is,
99.554
tan o =
-30.656
6 = tan 9.354
4 = -72. 885'
