The tension in cable AD is 570N From the perspective of point A provide the force vector in CVF.
Also give the scalar value listed
360 mm 450 mn P. s : 500 min 320 mm \" . 600 mmSolution
>> Writing all the coordinates :
A = (0, - 600, 0) mm = (0, -0.6, 0) m
B = (450, 0, 0) mm = (0.45, 0, 0) m
C = (0, 0, -320) mm = (0, 0, -0.32) m
D = (- 500, 0, 360) mm = (- 0.5, 0, 0.36) m
>> Now, Let Tensions in cables are : Tab, Tac and Tad
>> Considering Tab
It is acting along AB
and, AB = (0.45 i) - (- 0.6 j) = 0.45 i + 0.6 j
Magnitude = [0.452 + 0.62]1/2 = 0.5625
So, Unit Vector along AB = (0.45 i + 0.6 j)/0.5625 = 0.8 i + 1.0667 j
=> Tab = Tab(0.8 i + 1.0667 j)
>> Considering Tac
It is acting along AC
and, AC = (- 0.32 k) - (- 0.6 j) = - 0.32 k + 0.6 j
Magnitude = [0.322 + 0.62]1/2 = 0.68
So, Unit Vector along AC = ( - 0.2 k + 0.6 j)/0.68 = 0.882 j - 0.471 k
=> Tac = Tac(0.882 j - 0.471 k)
>> Considering Tad
It is acting along AD
and, AD = (- 0.5 i + 0.36 k) - (- 0.6 j) = - 0.5 i + 0.6 j + 0.36 k
Magnitude = [0.52 + 0.62 + 0.362]1/2 = 0.86
So, Unit Vector along AD = ( - 0.5 i + 0.6 j + 0.36 k)/0.86 = - 0.58 i + 0.698 j +0.419 k
=> Tad = Tad(- 0.58 i + 0.698 j +0.419 k)
>> Now, under Equilibrium, Net Forces = 0
=> Tab + Tac + Tad = 0
=> Tab(0.8 i + 1.0667 j) + Tac(0.882 j - 0.471 k) + Tad(- 0.58 i + 0.698 j +0.419 k) = 0
As, Tad = 570 N given
>> Now, Comparing Coefficients,
=> 0.8*Tab - 0.58*Tad = 0 , => Tab = 413.25 N
>> - 0.471*Tac + 0.419*Tad = 0 , => Tac = 507.07 N
