During a storm, a tree limb breaks off and comes to rest across a barbed wire fence at a point that is not in the middle between two fence posts. the limb exerts a downward force of 286 n on the wire. the left section of the wire makes an angle of 12.7° relative to the horizontal and sustains a tension of 433 n. find the (a) magnitude and (b) direction (as an angle relative to horizontal) of the tension that the right section of the wire sustains.

Explanation:

Weight, W = 286 N

Tension in the left wire, T1 = 433 N

α = 12.7°

let the tension in the right wire is T2 and angle with the horizontal is β.

Make the components and maintain the equilibrium

(a)

Equilibrium of forces along x axis

   .... (1)

Equilibrium of forces along y axis

    .... (2)

Squarring equation (1) and (2) and then add

T2 = 463.5 N

(b) Divide equation (2) by (1)

β = 24.2°

(a) T2 be the tension in right wire

this allows people to make the best decision or pursue the best option. when alternatives are weighed using their advantages and disadvantages, the option whose disadvantages outweigh the advantages (based on a qualitative or quantitative analysis) are shunned while those whose advantages outweigh their disadvantages are pursued.
