Find the tension in the two cords shown in the figure above. Neglect the mass of the cords, and assume that the angle is 38° and the mass m is 220 kg
[Take g = 9.8 ms-2]
T1 = 2864 N, T2= 3612 N
T1= 3612 N, T2 = 2864 N
T1= 3502 N, T2= 2760 N
T1 = 2760 N, T2 = 3502 N
Correct answer is C
W = mg = 220 x 9.8 = 2156 N
⇒Sin 38º = 2156T1
⇒ T1 = 2156Sin38
⇒ T1 = 3502 N
Cos 38º = T2T1
⇒ T2 = 3502 x Cos 38º
⇒ T2 = 2760 N
; T1 = 3502 N, T2 = 2760 N.
