Question

Three light strings are connected at the point P. A weight W is suspended from one of the strings. End A of string AP and end B of string PB are fixed as shown. In equilibrium PB is horizontal and PA makes an angle o 60 with the horizontal. If the tension in PB is 30 N then what is the tension in PA and weight W are respectively?

Answer 1

Force balance

$Tsin{30}^0=30N$

$T=60N$

$W=Tcos{30}^0$

$W=30\sqrt{3}$

Tension the string AP is 60N and weight W is $30\sqrt{3}$
