    Answer:

    The torque of the wheel is 0.92 N-m.

    Explanation:

    Given that,

    Radius of wire = 3 cm

    Angular acceleration = 92.00 rad/s²

    Suppose, Mass of wheel is 4 kg and radius is 5 cm. find the torque of the wheel.

    We need to calculate the torque of the wheel

    Using formula of torque

    \tau=I\alpha

    \tau=MR^2\times\alpha

    Where, M = mass of wheel

    R = radius of wheel

    \alpha = angular acceleration

    Put the value into the formula

    \tau=4\times(5\times10^{-2})^2\times92

    \tau=0.92\ N-m

    Hence, The torque of the wheel is 0.92 N-m.
