A flywheel should go from angular velocity ω0 to final angular velocity ωE in 2.5 revolutions can be accelerated evenly. The energy should increase by x%. a) In general, state ωE (x) as a function of x and sketch the course qualitatively. b) The acceleration is to be caused by a tangential force acting at a distance l from the axis of rotation Force F are generated. The absolute change in energy is at 2.5 revolutions 3000 J (only applies to part b) !). Sketch F(l) as a function of l and calculate the value F(l=0.8m). c) The arrangement is fully decelerated. Give general the needed Braking power P(ωE) as a function of ωE and sketch the course qualitatively.
