An ogre has a mass of 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 to the bridge at the point 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?

a

15000 n

b

35500 n

c

25500 n

d

45000 n
