1.) A girl weighing 620 N sits in the middle of a 2.8-meter long hammock which sags 1.2 m below the point of support. What force is exerted by each of the sags of the two ropes supporting the hammock?
2.) A uniform bar is 4 m long. It weighs 300 N. At one end, 1 m from the pivot point, there is a resisting weight of 2000 N. What force must be applied at the other end to produce equilibrium?
thanks a lot!

I can recommond a site to you from where you can do all your physics related queires without any doubt. But be sure if you are going to join their forum, be absolutely polite and ask them questions. They are the Professors like Massachusetts Institute of Technology(MIT)and they are giving the service for free. The Site deals with other areas, but physics is one of them. Just try and i can assure you it will boost your knowledge in areas of physicas whatever you say .. Just check it out here only.. http://ocw.mit.edu/OcwWeb/Physics/index.htm . Here you can find both audio video recordings of the professors for free..
