A) 10 N, 11 N
B) 10 N, 6 N
C) 10 N, 10 N
D) Can't calculate due to insufficient data
Correct Answer: C
Solution :
By drawing the free body diagram of point B Let the tension in the section BC and BF are \[{{T}_{1}}\] and \[{{T}_{2}}\]respectively. From Lami's theorem \[\frac{{{T}_{1}}}{\sin 120{}^\circ }=\frac{{{T}_{2}}}{\sin 120{}^\circ }=\frac{T}{\sin 120{}^\circ }\] Þ \[T={{T}_{1}}={{T}_{2}}=10\ N.\]You need to login to perform this action.
