A motor has a rotor (with armature) of moment of inertia m . The rotor is attached to a gear box of gear ratio G > 1. The output of the gearbox is attached to a mass whose moment of inertia is . What will be the moment of inertia ‘felt’ by the motor? What will be the moment of inertial ‘felt’ by someone who is rotating the mass by hand, to turn the motor? Which of the two is large

Explain the difference between each pair of concepts. a. frequency and relative frequency b. percentage and relative frequency a. select the correct choice below. a. frequency is the total number of observations in a data set. relative frequency is the number of times a particular distinct value occurs. b. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of a value to the total number of observations. c. frequency is the total number of observations in a data set. relative frequency is the ratio of the number of times a particular distinct value occurs to the frequency. d. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of two different values.
