The design of a 60.0 cm industrial turntable requires that it has a kinetic energy of 0.250 j when turning at 45.0 rpm. What must be the moment of inertia of the turntable about the rotation axis

The moment of inertia of the turntable about the rotation axis is 0.0225 kg.m²

Explanation:

Given;

radius of the turnable, r = 60 cm = 0.6 m

rotational kinetic energy, E = 0.25 J

angular speed of the turnable, ω = 45 rpm

The rotational kinetic energy is given as;

where;

I is the moment of inertia about the axis of rotation

ω is the angular speed in rad/s

Therefore, the moment of inertia of the turntable about the rotation axis is 0.0225 kg.m²

learn it on the intertant so you can solve

the results is a decrease in air temperature with an increase of altitude.
