Torque Sum with applied torque off axis

Click For Summary
SUMMARY

The discussion centers on calculating the sum of torques in a free body diagram, specifically addressing the handling of an applied torque at a point different from the pivot point. It is established that the torque remains consistent regardless of the point about which it is calculated. The conversation emphasizes the importance of understanding the concept of a couple, which consists of equal and opposite forces, in torque calculations.

PREREQUISITES
  • Understanding of free body diagrams
  • Basic principles of torque and rotational mechanics
  • Knowledge of the concept of a couple in physics
  • Familiarity with pivot points in torque calculations
NEXT STEPS
  • Study the principles of torque in rotational dynamics
  • Learn how to construct and analyze free body diagrams
  • Explore the concept of couples and their effects on torque
  • Investigate the relationship between applied forces and torque about different pivot points
USEFUL FOR

Students of physics, engineers, and anyone involved in mechanics or rotational dynamics who seeks to deepen their understanding of torque calculations and free body diagrams.

I think I'm missing something really simple here due to being out of school for a while:

In a free body diagram, if I am trying to take the sum of torques about point 1, how should I deal with an applied torque at point 2? See attached sketch

Hi Xevuhtess7! Welcome to PF! :smile:

Do you mean a couple, a pair of equal and oposite forces?

The the torque is the same about any point. :wink:
