Torque Due to Weight Video Lessons

Concept

# Problem: A 4m, 500kg steel beam extends horizontally from the point where it has been bolted to the framework of a new building under construction. a 70kg worker stand at the far end of the beam. What is the magnitude of the torque about the point where the beam is bolted into place.

Torque equation:

$\overline{){\mathbit{\tau }}{\mathbf{=}}{\mathbit{r}}{\mathbit{F}}{\mathbf{sin}}{\mathbit{\theta }}}$ where θ is the angle between r and F.

Στ = τbar + τworker
