A weight of 10N is supported by 2 strings AB and AC tied to a horizontal support.The strings makes an angle of 30 degree and 60 degree inclined respectively to the horizontal support.calculate the tention T1 and T2 in the strings
The system is in equilibrium:
30o W. of N. = 120o CCW.
T1*Cos120 = -T2*Cos60.
T1 = T2.
T1*sin120 + T2*sin60 = -(-10) = 10.
T2*sin120 + T2*sin60 = 10,
0.866T2 + 0.866T2 = 10, T2 = 5.77 N.
T1 = T2 = 5.77 B.
