Again what type vector of this force can be? (20%) 2. As shown, calculate the magnitude of the moment about the base point O of the 600-N force in two different ways (15%). 3. What is a couple-moment in mechanical sense? Again explain why is it a free vector? (30%) 4. Try to illustrate by plotting a force-moment system in a plane can be replaced by a single force in the same plane. (20%) 5. As shown, the masthead fitting supports the two forces in the figure. Determine the magnitude of force T which will cause no bending of the mast (zero moment) at point O (15%). --
