STEM Lessons for College Students

14.40 .. A uniform solid metal disk of mass 6.50 kg and diameter 24.0 cm hangs in a horizontal plane supported at its center by a vertical metal wire. You find that it requires a horizontal force of 4.23 N tangent to the rim of the disk to turn it by 3.34_ thus twisting the wire. You now remove this force and release the disk from rest. (a) What is the torsion constant for the metal wire? (b) What are the frequency and period of the torsional oscillations of the disk? (c) Write the equation of motion for u1t2 for the disk.

I have not created a lesson for this question yet.

Please leave a comment below with specifics about the question, and I will make a detailed lesson on it as soon as possible. (I can usually have something up within a day.)

NEED IMMEDIATE HELP? Get the student solution manual here: University Physics Manual otherwise, I should be able to get a video lesson up within a day or so.
