What is a good blue longboard cruising wheel?

How much work does the motor need to do to bring the stationary wheel up to cruising speed?

  • A ferris wheel rotates because a motor exerts a torque on the wheel. the radius of the london eye, a huge observation wheel on the banks of the thames isn 67.5 , and its mass us 1.90x10^6 kg. the cruising angular speed of the wheel is 3.50x10^-3 rad/s. how much work does the motor need to to bring the stationary wheel up to cruising speed?

  • Answer:

    kinetic energy = 0.5*m(wr)^2 I presume the radius is 67.5 meters. Then, reqd work = 53023 J = 53.023 kJ
