Aflywheel of j = 50 kg-m2 initially standing still is subjected to a constant torque. if the angular velocity reaches 20 hz in 5 s, find the torque given to the flywheel.

Explanation:

given,

J = 50 kg-m²

frequency, f = 20 Hz

time ,t = 5 s

we know,

angular velocity = 2 π f

ω = 2 π x 20

ω = 125.66 rad/s

now, angular acceleration calculation

   α = 25.13 rad/s²

Torque given to the flywheel.

Torque of the given  flywheel is equal to

some think that theories become laws, but theories and laws have separate and distinct roles in the scientific method. a law is a description of an observed phenomenon in the natural world that hold true every time it is tested. it doesn't explain why something is true; it just states that it is true.
