- Determine the resultant moment of the forces acting about the x, y, and z axes. Suppose that F1=250N, F2=90N, F3=105N, and F4=310N.arrow_forwardThe pipe assembly is subjected to the force of F = 80 N. Determine the i component (in N-m) of the moment of this force about point B, if a = 40° and ß = 25°. The position of C from A is defined by following values: L₁ = 0.25 m, L₂= 0.3 m, and L3 = 0.25 m. Your Answer: L2 F a 0.4 m Liarrow_forwardThe force of F = 80 lb acts along the edge DB of the tetrahedron. Determine the magnitude of the moment of this force about the edge CA. If the moment of the force F about the edge CA of the tetrahedron has a magnitude of M = 200 lb-ft and is directed from C toward A, determine the magnitude of F.
