Question

_________

  
b) Which of the following describes the value of in a) [Select all that are correct]?

The amount of torque necessary for each unit of moment of inertia

The amount of torque necessary for each unit of rotation

The amount of moment inertia for each unit of torque

The amount of mass for each unit of diameter

The amount of moment inertia for each unit of rotation




c) How much time will it take the turntable to reach an angular velocity of f if it starts from rest?  

__________


d) Which of the following describes the value of in c) [Select all that are correct]?

The time interval for one unit of increase in angular displacement

The amount of change in the angular velocity in each unit of torque

The time interval for one unit of increase in angular velocity

The amount of change in the angular velocity in each unit of time

The amount of angular displacement in each unit of time

Explanation / Answer

a) Moment of inertia of turnable, I = 0.5*M*R^2

= 0.5*M*(d/2)^2

= M*d^2/2

now Apply, Torque = I*alfa

= M*d^2*alfa/2

b) 1) The amount of torque necessary for each unit of moment of inertia

c) Apply, wf = wi + alfa*t

==> t = (wf - wi)/alfa

= (wf - 0)/alfa

= wf/alfa

d) 4) The amount of change in the angular velocity in each unit of time
