SUMMARY

The discussion focuses on the challenge of stopping a disc rotating in simple harmonic motion (SHM) with a dynamic force of 14,400N at a speed of 2.43 RPM. Participants inquire about the availability of electromagnets capable of exerting forces greater than 1,000N and seek guidance on calculating magnetic field resistance. Clarifications are requested regarding the nature of the force (oscillating vs. steady) and the materials involved in the setup. Suggestions include using multiple electromagnets to enhance stopping power and considering frictional forces as a deceleration factor.

PREREQUISITES
  • Understanding of simple harmonic motion (SHM) principles
  • Knowledge of electromagnet specifications and force calculations
  • Familiarity with centripetal force concepts
  • Basic mechanical engineering principles regarding friction and deceleration
NEXT STEPS
  • Research high-force electromagnets suitable for mechanical applications
  • Learn about calculating magnetic field resistance in electromagnets
  • Explore methods for chaining electromagnets to increase stopping force
  • Investigate the effects of friction on rotating systems and deceleration techniques
USEFUL FOR

Mechanical engineers, students studying dynamics, and professionals involved in designing systems that require controlled stopping of rotating machinery.

first time guys.
i have a disc with a bearing and a shaft through it. the disc is rotating in simple harmonic motion with a dynamic force of 14400N and speed of 2.43 rpm. i need to use electromagnets to stop this disc from rotating.
questions.
-where or can can i get electromagnets to stop 14400N . the max i have found is just 1000N
- what calculations do i need to consider in calculating magnetic field resistance.

What do you mean when you say that the disk is rotating with SHM? Is it rotating, or is it translating side to side? Is the 14400 N an oscillating force, or is it steady?Can you provide a sketch of the situation? This would probably help a lot. Please specify the materials for the parts also.
 
what is providing that 14400 N of force (I'm assuming that is centripetal force?)
If you stop that source, the disk will eventually stop due to friction with the bearings, and the air.
Applying an extra 1000 N of force will assist with that deceleration.
can you chain the magnets together? have one magnet on one side, and another magnet on the other side?
