On speeding up:
τload - τfriction = Iαup
On speeding down:
τfriction = Iαdown
If i substitute τfriction from speeding down to speeding up equation, i get moment of inertia:
I = (τload)/(αup+αdown)
But, is this allowed? Does friction torque in speeding up is equal to friction torque in...
Problem Statement: Let there be a ring of mass m and radius r. Let 3 masses be attached to the ring and named as O,P and Q. Mass of O and Q is 2m and mass of p is M. The angle between 2 masses is 15 degrees as shown in the figure.
Find the maximum velocity the ring must roll so that it doesn't...
Hello, I was recently given the task to find experimentally the moment inertia of a sphere. I thought of rolling the sphere down an inclined plane and applying conservation of energy to the sphere. The equations i came up with are: mgh = 1/2mv2 + 1/2Iω2 solving for v^2 we come up with the...
Suppose i have an equilateral triangle and i want to find the principal axes of rotation passing through one of the vertex. How can i do that? I am thinking along the following lines but i'm not too sure:
1)Since the equilateral triangle has symmetry about a median, that definitely is one...
1. Homework Statement
A 45 RPM record is a disk with a wide hole in the center. The mass of such record is 45g. It is 7 inches in diameter, and the hole in the center has a 1.5 inch diameter. (Sorry for the odd units, this was the way it was given).
Find the moment of inertia of the 45 RPM...
I need to make a project that integrates physics with math, involving the use of integrals to find moment inertia of areas. The theory could be read here :http://www.intmath.com/applications-integration/6-moments-inertia.php
I need to make an object that applies the theory above. Can anybody...
