An initially installed flywheel can store 10 J of kinetic energy when rotating at 300 rad/s. It is replaced by another flywheel of the same size but made of a stronger material. If its mass is the same as that of the original, and it is now capable of achieving a rotational speed of 425 rad/s, what maximum energy can be stored? 2.01E+6J O 1.66E+3J O 1.73E+5 J O 1.00E+6J

Some European trucks run on energy stored in a rotating
flywheel, with an electric motor getting the flywheel up to its top
speed of 160 π rad/s. One such flywheel is a solid, uniform
cylinder with a mass of 270 kg and a radius of 1.07 m. (a) What is
the kinetic energy of the flywheel after charging? (b) If the truck
uses an average power of 6.2 kW, for how many minutes can it
operate
between chargings?

It has been suggested that we should use our power plants to generate energy in the off-hours (such as late at night) and store it for use during the day. One idea put forward is to store the energy in large flywheels. Suppose we want to build such a flywheel in the shape of a hollow cylinder of inner radius 0.490 m and outer radius 1.60 m , using concrete of density 2250 kg/m3. If, for stability, such a heavy...

Trucks can be run on energy stored in a rotating flywheel, with an electric motor getting the flywheel up to its top speed of 627 rad/s. One such flywheel is a solid, uniform cylinder with a mass of 461 kg and a radius of 1.5 m that rotates about its central axis. What is the kinetic energy of the flywheel after charging? (Submit Answer) Tries 0/5 If the truck uses an average power of 8.4 kW, for how many minutes...

1) The parallel axis theorem provides a useful way to calculate the moment of inertia I about an arbitrary axis. The theorem states that I = Icm + Mh2, where Icm is the moment of inertia of the object relative to an axis that passes through the center of mass and is parallel to the axis of interest, M is the total mass of the object, and h is the perpendicular distance between the two axes. Use this theorem and...
