# Question Solved1 Answer4.8 FURTHER SIT 120. Replace the loading on the frame by a single force. Specify where its line of action intersects a Vertical line along member AB, measured from A. 4121. Replace the loading on the frame by a single resultant force. Specify where its line of action intersects a horizontal line along member CB. measured from end C. -1 m- 0.5 m 600 NA so 4.8 FURTHER SIT 120. Replace the loading on the frame by a single force.
