Problem 2 A 500-pound force is acting on an eye bolt as shown. Determine the moment about point B caused by the force as a Cartesian vector and the magnitude of the resultant vector. The coordinates of point A are (1,2,1) inches and the coordinates of point B are (0,-5,0) inches. (Hint: B+50°) Z-axis x=40° x-axis 8=120° F+500 3-axis

Calculate the resultant moment produced by two forces about point O. Express the result as a Cartesian vector.

2/35 Calculate the moment of the 250-N force on the handle of the monkey wrench about the center of the bolt. 250 N 153 200 mm- 30 mm Problem 2/35

Express and identify the resultant of the two forces and one couple shown acting on the shaft angled in the x-z plane. Assume F = 500 lb, M = 490 lb-ft, a = 8 in., b = 22 in., 0 = 12° -M Answer: M=(1 -21.52 j+ i 12.57 k) lb-in. 300

The 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. D 5 ft A F 15 ft 8 ft 10 ft 4 ft B
