## Homework Statement

A 3.60-m-long, 500 kg steel uniform beam extends horizontally from the point where it has been bolted to the framework of a new building under construction. A 70kg construction worker stands at the far end of the beam

What is the magnitude of the torque about the bolt due to the worker and the weight of the beam?

(there was no diagram)

## Homework Equations

torque = m*d

## The Attempt at a Solution

I just summed the torques around the bolt and considered the beam as having all its mass at its center:

torque from beam: t = 360kg(9.8)(1.8m) = 6350.4N*m

torque from person: t = 70kg(9.8)(3.6) = 2469.6N*m

2469.6N*m + 6350.4N*m = 8820N*m

Is this correct and is my reasoning about beam as having its mass at midpoint correct? thanks for any help
