For an object subjected to one or more forces, there are two force cases to consider. What are the two cases?

Replace the loading on the frame (Figure 1) by a single resultant force. Suppose that F = 150 lb, F2 = 50 lb, and M = 500 lb · ft. Part A Determine the magnitude of the resultant force. Express your answer to three significant figures and include the appropriate units. • View Available Hint(s) HA FR = Value Units Figure 1 of 1 Submit 2 ft Part B Determine the angle between the resultant force and the x axis. Express your answer in degrees to three significant figures. 4 ft • View Available Hint(s) M vec -3 ft 30* measured counterclockwise from the positive x axis

clockwise. (This is the info missing from the Question 2.PNG) Look at the images for details about the question.

2- In order to determine the effects of a force, acting on a body, we must know A. magnitude of the force B. line of action of the force C. nature of the force (pull or push) D. All of the above
