Problem 39E

The rope is repositioned as shown and still supports the 50-N lantern. Is the tension in the rope less than, equal to, or more than 50 N? Use the parallelogram rule to defend your answer.

Step-by-Step Solution:
Step 1 of 3

Parallelogram rule states that if two vectors acting simultaneously at a point can be represented both in magnitude and direction by the adjacent sides of a parallelogram drawn from a point,then the resultant vector is represented both in magnitude and direction by the diagonal of the parallelogram passing through that point. Consider there are two pieces of the rop supporting to 50 N of the lantern so each piece needs to support less than the full 50 N. if both pieces of rope were vertical,they would needs to support only one-half of the 50 N weight.since they are at some other angle,the tension will be need to be more than 25 N,but it will be still less than 50 N.
