    A riveting machine is driven by a motor of 3 KW. It takes 1 sec and 12...
    First, we need to calculate the angular acceleration of the flywheel during the riveting operation:

    Power = Work/Time
    3 KW = 12 KN-m / 1 sec

    Angular acceleration = (Work/Energy) / Moment of Inertia
    = (12 KN-m / 3 KW) / 55 (kg m^2)
    = 0.0727 rad/s^2

    Next, we can use the equation for rotational kinetic energy to find the final speed of the flywheel:

    Rotational kinetic energy = 1/2 * Moment of Inertia * (Final angular speed)^2

    We know the initial angular speed is 360 rpm, or 37.7 rad/s. Solving for the final angular speed:

    Final angular speed = sqrt(2 * Rotational kinetic energy / Moment of Inertia)
    = sqrt(2 * 0.5 * 55 * (37.7^2 + 2 * 0.0727)) / 55
    = 43.6 rad/s

    Converting to rpm:

    Final speed = 43.6 * 60 / (2 * pi)
    = 413 rpm

    Therefore, the speed of the flywheel immediately after riveting is 413 rpm.
