ENGR 211 Lecture 10 Fall 2007 Civil Engineering Frames and Machines Frames and Machines • Objects are made up of pieces that are fastened together • Analysis may involve one piece, some combination of pieces or the whole object. • Advice: Start analyzing! Clearly define each subject with a FBD and then jump in. Civil Engineering Frames and Machines Frames and Machines Some Hints Some Hints • Look for two force members (they may not be straight!) – Draw forces acting along the line of action between them. • Carefully draw FBD’s – At contact points, forces are equal and opposite (action and reaction) • Apply External Forces to one member only
