Moment of Inertia (not through symmetry axis)

Click For Summary
SUMMARY

The moment of inertia for a solid cylinder with a mass of 8.41 kg and a radius of 7.5 cm, rotating about an axis parallel to the symmetry axis but passing through the edge, can be calculated using the parallel axis theorem. The relevant equations are I = 0.5mr² for the moment of inertia about the center and I = Icenter + mr² for the parallel axis adjustment. By substituting the values into these equations, one can derive the correct moment of inertia for this specific rotation scenario.

PREREQUISITES
  • Understanding of moment of inertia concepts
  • Familiarity with the parallel axis theorem
  • Basic knowledge of rotational dynamics
  • Ability to perform calculations involving mass and radius
NEXT STEPS
  • Study the derivation of the parallel axis theorem
  • Learn about moment of inertia for different shapes and axes
  • Explore applications of moment of inertia in engineering
  • Investigate the effects of mass distribution on rotational motion
USEFUL FOR

Students in physics or engineering courses, educators teaching rotational dynamics, and anyone interested in understanding the principles of moment of inertia in mechanical systems.

Homework Statement


What is the moment of inertia of a solid cylinder (of mass 8.41kg and radius 7.5cm) rotating about an axis parallel to the symmetry axis but passing through the edge of the cylinder?

Homework Equations


I=.5mr2,
but how does this change when the axis is passing through the edge of the cylinder?

The Attempt at a Solution


I can't attempt it intelligently until I have the correct equation. Once I do, I can finish it off myself.

You will need the parallel axis theorem:

I=Icenter+mr2
 
Thanks so much!
