Calculate the torque about the left support due to the truck

- PHYSICS -
**bobpursley**, Wednesday, March 2, 2011 at 8:11pmWouldn't it depend on the weight of the bridge? OK, the bridge is massless.

about the left side: 9000*.6 is the torque due to the truck. Of course, the bridge weight matters, as does the right support holding half the bridge.

And I tried 9000*.6 and it's still saying i'm wrong.

This is kind of what the diagram looks like. O is the truck
