A drive is to be uprated to twice its speed. The braking system must then absorb

  • A.the same energy in each stop
  • B.half the energy in each stop
  • C.four times the energy in each stop
  • D.twice the energy in each stop

Answer: C

Because stored energy follows the square of the speed, a speed uprating is far more demanding on the braking system than on the motoring side. Resistors, choppers and friction linings all need reassessment before such a change is made.
