SUMMARY

This discussion focuses on the concept of torque in relation to two squares of different sizes but equal mass. When a force is applied to the corner of the smaller square, the resulting torque is less than that applied to the larger square due to the distance from the center of mass (CM). Additionally, the moment of inertia of the larger square is greater, which affects its rotational dynamics. The conversation emphasizes the importance of understanding torque and moment of inertia in physics.

PREREQUISITES
  • Basic understanding of torque and its calculation
  • Familiarity with the concept of center of mass
  • Knowledge of moment of inertia and its significance in rotational motion
  • Fundamental principles of physics related to forces and motion
NEXT STEPS
  • Study the mathematical formulation of torque and its applications in physics
  • Explore the relationship between moment of inertia and angular acceleration
  • Investigate real-world applications of torque in engineering and mechanics
  • Learn about the effects of varying force application points on torque in different shapes
USEFUL FOR

Students of physics, educators teaching mechanics, and anyone interested in understanding the principles of torque and rotational motion.

Just tryin to wrap my head around it, say I've got 2 squares(only worrying about 2d), assuming one is twice the size as the other but same mass.
if i push on the corner of the small square there is less toque than if i did the same push on the large box since its conact point is further from the cm?


just a simple example id like clarrified to help me understand better

I assume you are talking about the torques about the centres, generated by equal forces. Then:
True , but the moment of inertia of the bigger square is largest.

cheers, yeah i was thinking of the simple case

thanks for the answer, does help...sorta new it myself but wanted to hear it from someone else...
