Answer to Question #287552 in Physics for kevs

Question

find the tension in the strings ab and bc in the figure shown if the suspended weight is 30 N

Answer 1

For an isosceles triangle configuration, we have

$$T_{AB}=T_{BC}=\dfrac W{2\sin(\theta/2)}=15/\sin(\theta/2).$$

In the equation, $\theta$ is the angle between the strings.
