Question

Consider the following two statements A and B and identify the correct choice.
A) Spokes are used in a bicycle wheel to increase the strength of wheel.
B) Mass of fly wheel is concentrated on its rim to increase its moment of inertia.

• A. A is true but B is false
• B. A is false but B is true
• C. Both A and B are true
• D. Both A and B are false

Answer 1

Answer: (B)

A is false but B is true

(A) Spokes are used to decrease the the moment of inertia keeping the mass of the wheel less which help in increasing angular velocity of the wheel.
(B) Mass of the fly wheel is concentrated on its rim so it increases the moment of inertia.
