Moment Of Inertia Of A Vinyl Record

Given that the moment of inertia of a solid uniform disc of mass m and radius r is i 1 2mr 2 estimate the rotational quantum number when the disc is rotating at 33 r p m.

Moment of inertia of a vinyl record.

The moment of inertia of an object is a calculated measure for a rigid body that is undergoing rotational motion around a fixed axis. Area moment of inertia or moment of inertia for an area also known as second moment of area i is a property of shape that is used to predict deflection bending and stress in beams. The smith street band. That is to say it measures how difficult it would be to change an object s current rotational speed.

A horizontal vinyl record of mass 0 10 kg and radius 0 1 m rotates freely about a vertical axis through its center with an angular speed of 4 7 rad s. A horizontal vinyl record of mass 0 10 kg and radius 0 10 m rotates freely about a vertical axis through its center with an angular speed of 4 7 rad s and a moment of inertia of 5 0 10 4 kg m2.

Customary system m is in slugs 1 slug 32 2 pounds and r in feet with i expressed in terms of slug foot square. The unit of moment of inertia is a composite unit of measure. A 5 points use the table at the end of this exam to determine the moment of inertia of the vinyl record b 6 points if the vinyl record is given an angular acceleration of a 4 rad s how much torque did the record player apply to the vinyl record. 1 cm 4 10 8 m 4 10 4 mm 4.

Putty of mass 0 020 kg drops vertically onto the record from above and sticks to the edge of the record. A typical vinyl record has a mass of about 175g and a diameter of about 30 cm. In the international system si m is expressed in kilograms and r in metres with i moment of inertia having the dimension kilogram metre square. The moment of inertia of any body having a shape that.
