A) 280 Hz
B) 360 Hz
C) 56 Hz
D) 56.0 Hz
Correct Answer: C
Solution :
Horizontal force cancil out at A and B and C \[{{F}_{u}}\]at \[A=2F\sin 60\] \[{{F}_{u}}\]at \[B=F\sin 60\] \[{{F}_{u}}\]at \[C=F\sin 60\] and point AB and C forces acts hence no equilibrium.You need to login to perform this action.
