SUMMARY

The discussion focuses on calculating the torques for a cylinder's point of mass, specifically addressing the challenge of determining the appropriate pivot point for torque calculations in case b. The user has successfully solved case a but seeks guidance on summing torques using integrals. It is established that taking the cylinder's center of mass as the pivot point is a viable approach for simplifying the calculations.

PREREQUISITES
  • Understanding of torque and its calculation methods
  • Familiarity with integrals in physics
  • Knowledge of the center of mass concept
  • Basic principles of rotational dynamics
NEXT STEPS
  • Research the application of torque in rotational dynamics
  • Study the use of integrals for calculating torques
  • Explore methods for determining the center of mass in various shapes
  • Learn about different pivot points and their impact on torque calculations
USEFUL FOR

Physics students, mechanical engineers, and anyone involved in dynamics and rotational motion analysis.

I already got the answer for the case a
but at the case b, i don't know how to sum all of the torques.
I'm thinking of using integral, but i don't know where to put the pivot point for the torque.
I don't know how to search for the pivot point.
Can anybody give me hints so i could find the pivot point ?

take cylinder's center of mass for a pivot point for example
