*A 1.1 kg bird feeder hangs from a horizontal tree branch. The bird feeder is attached to the branch at a point that is 1.1 m from the trunk. What is the amount of torque exerted by the bird feeder on the branch? The origin is at the pivot point, where the branch attaches to the trunk.*

Given: 1.1 kg mass

1.1 m from trunk, which is the origin of the system.

Objective: Find the amount of torque exerted by the bird feeder on the branch.

Battle Plan:

Find the force exerted by the bird feeder from the mass.

Multiply the distance from the trunk by the mass of the bird feeder

Outcome:

Force = mass x acceleration

Force = 1.1 kg x 0m/s^2

Force = 0 N

0 N x 1.1 m = 0 N*m

Given: 1.1 kg mass

1.1 m from trunk, which is the origin of the system.

Objective: Find the amount of torque exerted by the bird feeder on the branch.

Battle Plan:

Find the force exerted by the bird feeder from the mass.

Multiply the distance from the trunk by the mass of the bird feeder

Outcome:

Force = mass x acceleration

Force = 1.1 kg x 0m/s^2

Force = 0 N

0 N x 1.1 m = 0 N*m

My real question is, how do I get newtons from the mass of that birdfeeder? The feeder isn't accelerating anywhere, so the force has to be zero, right?

But they tell me the answer to this problem is 2.83e4 N*m.

I'd appreciate your help.
