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

Answer 1

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.
