esultant about the point. This important theorem is proved in books on mechanics. The re-sultant moment may be called the moment of the system. For example, two downward vertical forces, 8 ft. apart, each of 10lbs., have moments of 60 and —20 ft.-lbs. about an intermediate pointK, distant 6 ft. and… … 5ccvt. Examples on Problems 409 to 413. *1. Copy the jointed frame double size with the supports placed atthe same level. The loads at the two upper joints, and thesupporting forces P and Q, are all vertical. Draw the forcediagram for the frame to a scale of J to 100 lbs., and measure/and Q. Ans.…
