For the following force system, determine:
1. The equivalent force system by simplifying the distributed load into concentrated loads.
2. The equivalent force system (resultant force and couple moment) acting at point A.
3. The equivalent force system with just the resultant force and find where its line of action intersects with the beam, measured from point A.
Do we need to know where the couple moment of 1500 N-m is applied? 900 N/m, 600 N/m, 1500 N-m, 3 m.
