Use the law of sines and the law of cosines, in conjunction with sketches of the force triangles, to solve the following problems. Determine the magnitude of the resultant R and the angle e between the x-axis and the line of action of the resultant for the following: 400 Ib 29 480 Ib 21°

3. A beam is subjected to distributed loads as shown in Figure 3. Determine the magnitude and location of the resultant of the distributed forces. Answer: (1) Magnitude: (2) Location: A 300 lb/ft 6' 4' Figure 3 60 lb/ft 10' B

1) Determine the magnitude of the resultant force. Express your answer in pounds to three significant figures 2) Determine the angle between the resultant force and the x axis. Express your answer in degrees to three significant figures. 3) Determine the couple moment at point A. Express your answer in pound-feet to three significant figures. Enter positive value if the moment is counterclockwise and negative value if the moment is clockwise.
