A wagon wheel consists of 8 spokes of uniform diameter, each of mass ms and length L cm. The outer ring has a mass mring. What is the moment of inertia of the wheel

Respuesta :

Answer:

The moment of inertial of the wheel,  [tex]I = 8(\frac{1}{3}M_sL^2 ) + M_rL^2[/tex]

Explanation:

Given;

8 spokes of uniform diameter

mass of each spoke, = [tex]M_s[/tex]

length of each spoke, = L

mass of outer ring, = [tex]M_r[/tex]

The moment of inertial of the wheel will be calculated as;

[tex]I = 8I_{spoke} + I_{ring}[/tex]

where;

[tex]I_{spoke[/tex] is the moment of inertia of each spoke

[tex]I_{ring[/tex] is the moment of inertia of the rim

Moment of inertia of each spoke [tex]=\frac{1}{3}M_sL^2[/tex]

Moment of inertial of the wheel

[tex]I = 8(\frac{1}{3}M_sL^2 ) + M_rL^2[/tex]
