Answer to Question #263232 in Physics for Haha

Question

4. A rope of negligible mass is stretched horizontally between two supports that are 3.44 m apart. When an

object of weight 3160 N hung at the center of the rope, the rope is observed to sag by 35.0 cm. What is

the tension in the rope?

Answer 1

The tension is

$$T=\frac{LF}{4s}=\frac{3.44·3160}{4·0.35}=7765\text{ N}.$$
