Question

The magnitude of the resultant of the two vectors in calculations for cable subjected to its own weight is always:

(a) Greater than one of the vector’s magnitude

(b) Smaller than one of the vector’s magnitude

(c) Depends on the angle between them

(d) Axis we choose to calculate the magnitude

The question was posed to me in quiz.

My question comes from Cables Subjected to its Own Weight in chapter Internal Forces of Engineering Mechanics

Answer 1

Correct option is (c) Depends on the angle between them

Explanation: Yes, the magnitude of the resultant of the two vectors always depends on the angle between them. It might be greater or smaller than one of the vector’s length. For perfectly saying, it does depend upon the angle between them.
