A constant torque of 23 N-m is applied to a shaft that is rotating with a CW angular velocity of 22.6 rad/s. Determine the time required to reverse the direction of motion and achieve a CCW rotation of 22.6 rad/s.

2.78 s

Explanation:

We are given that

Torque,

Initial angular velocity,

Final angular velocity,

Mass,m=2 kg

R=0.53 m

r=0.27 m

Moment of inertia of system=

Angular acceleration,

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
