7 (2 of 2) Resultant Force: Concurrent-Noncoplanar Force System | Statics of Rigid Bodies

In this video, we explore how to determine the Resultant Force in a Concurrent-Noncoplanar force system.

Here’s what we’ll cover:
1. Right-handed coordinate system
2. rectangular components of a vector
3. Cartesian unit vectors
4. Cartesian vector representation
5. Magnitude of a Cartesian vector
6. Coordinate direction angles
7. Unit vectors
8. Transverse and azimuth angles
9. Force Resultant of concurrent noncoplanar forces

We’ll also solve the following problems:
Problem 1: For the 100-lb force shown in the figure,
1. Express the force F as a Cartesian vector.
2. Compute the coordinate direction angles.

Problem 2: Two forces act on the hook shown in the figure. Specify the magnitude of F2 and its coordinate direction angles so that the resultant force FR acts along the positive y axis and has a magnitude of 800 N.
