Reduce the given loading system to a force-couple system at point A. Then determine the distance x to the right of point A at which the resultant of the three forces acts. A Answers: 8" V R= i M= 320 lb X= i Force-couple system at A. The force is positive if up, and the moment is positive if counterclockwise. Resultant i 15" 24" 600 lb 350 lb lb lb-in. in.

The girder in the frame is subject to a uniform load of w = 4060 N/m over its length L = 9.80 m.  a) What is the approximate moment in the girder at the face of the column at C? Use the standard sign convention for beams.  MC = ? b) What is the approximate maximum positive moment in the girder?  Mmax = ?
