An Ogre of mass 1000 kg and tries to walk across an 8 m drawbridge (from the castle side). The chain supporting the bridge is attached to the wall 12 m above the bridge and 5 m from the castle.

The Ogre stands 1 m from the end of the bridge, and the bridge itself is 20 degrees below the horizontal. If the bridge itself is 2000 kg, what is the tension in the chain?
