Question
change the force F to {30i+40j+80k} lb

Transcribed Image Text:**Problem Statement:**
*4–32. If **F** = {50i + 60j + 30k} lb, determine the magnitude and coordinate direction angles of the moment of **F** about point A.
**Diagram Description:**
The diagram depicts a 3D coordinate system with a pipe structure that includes several segments and angles.
- Point A is located at the origin where all three axes x, y, and z intersect.
- From point A, a horizontal segment runs 1 ft along the x-axis, then turns 90 degrees to run 2 ft parallel to the y-axis.
- At the end of this segment, the pipe extends upwards at a 45-degree angle for 3 ft towards point B.
- Force **F** is applied at point B, extending outwards from the pipe.
**Key Features:**
- The coordinate axes are labeled x, y, and z.
- The angle between the upward-extending pipe segment and the horizontal plane is 45 degrees.
- The problem requires calculating the moment of force **F** about point A, which involves understanding the cross-product of vectors and the concept of moments in physics.
