Calculating Torque and Lever Arm

Click For Summary
SUMMARY

The discussion centers on calculating torque using the formula Torque = Force x Lever Arm. Participants confirm that with a constant force, the lever arm's length is the sole determinant of torque. The user expresses uncertainty about their calculations for points B and C, while confirming their method of drawing a perpendicular line from the axis to the force line is correct, measuring 6 units. The conversation emphasizes the importance of accurately identifying the lever arm in torque calculations.

PREREQUISITES
  • Understanding of basic physics concepts, specifically torque.
  • Familiarity with the formula Torque = Force x Lever Arm.
  • Ability to visualize and draw perpendicular lines in geometric contexts.
  • Knowledge of how to measure distances accurately in a diagram.
NEXT STEPS
  • Study the principles of torque in rotational dynamics.
  • Learn how to calculate torque for various shapes and configurations.
  • Explore the effects of varying lever arm lengths on torque outcomes.
  • Investigate common mistakes in torque calculations and how to avoid them.
USEFUL FOR

Students studying physics, engineers working with mechanical systems, and anyone interested in understanding the principles of torque and lever arms.

Here is the problem http://imgur.com/6KRKJQu
Torque = force x lever arm
We are told that the force is all the same so the only thing that would determine the torque is the size of the lever arm. The ones that I'm not sure about are B and C. The rest I think I have done correctly. Just to make sure I'm doing it right though, I drew the line of the force straight down from D and drew a line from axis to this perpendicular and it measured to be 6. That's the correct method, correct?

correct :wink:

(do you mean B and F ?)

show us what you got for those :smile:
