Question

Three people located at​ A, B, and C pull on ropes tied to a ring. Find the magnitude and direction of the force with which the person at C must pull so that no one move

Answer 1

Answer:

Step-by-step explanation:

Three forces A, B and C pull on ropes tied to a ring such that ring  is in equilibrium.

For the ring to be in equilibrium the force must be concurrent i.e. there line of action must be passed through a single point.

There is no net force when  forces are concurrent.

When all three forces are equal then they should be at angle of $120^{\circ}$  to each other.
