Two ropes in a vertical plane exert equalmagnitude forces on

Two ropes in a vertical plane exert equal-magnitude forces on a hanging weight but pull with an angle of 72.0 degree between them. What pull does each rope exert if their resultant pull is 372 N directly upward?

Solution

Here ,

theta = 72 degree

resultant pull = 372 N

let the tension in each rod is T

2 * T * cos(theta/2) = resultant pull

2 * T * cos(72/2) = 372

T = 230 N

the force exerted by each rope is 230 N
