# Solution: Find the magnitude of the resultant force vector, R?

Assume the three force vectors intersect at a single point. F1 = i + 3j + 4k F2 = 2i + 7j – k F3 = -i + 4j + 2k What is the magnitude of the resultant force vector, R?

#### Problem Statement: ME Board October 1996

Assume the three force vectors intersect at a single point.

F1 = i + 3j + 4k

F2 = 2i + 7j – k

F3 = -i + 4j + 2k

What is the magnitude of the resultant force vector, R?

• A. 15
• B. 13.23
• C. 14.73
• D. 16.16

The magnitude of the resultant force vector, R is 15 units.
