7. Concrete pump is subjected to force \( F \) acting on point \( C \) as shown in the figure. Arms \( O A, A B \) and \( B C \) lie in the same plane which makes \( 35^{\circ} \) with \( x z \) plane. a) Determine the moment of force \( F \) about point \( O \). b) Determine the moment of force \( F \) about line \( O A \)

Step 1
Since the force F is acting in the plane that makes a 35° angle with the xz plane, we can use the following relationships: Fx = F * cos(35°) Fy = F * sin(35°) * sin(90°) Fz = F * sin(35°) * cos(90°) Now, let's find the position vectors of points A, B, and C with Show more…
