The door's moment of inertia for rotation about a vertical axis inside the door, 14 cm from one edge is 4.205 kgm².

Momnet of inertia about a vertical axis inside the door

The door's moment of inertia for rotation about a vertical axis inside the door, 14 cm from one edge is calculated as follows;

[tex]I = I_{cm} + Md^2[/tex]

where;

  • I, cm is the moment of inertia about central axis
  • d is the distance from the edge
  • M is mass of the door

[tex]d = \frac{L}{2} - 0.14\\\\d = \frac{0.91}{2} - 0.14\\\\d = 0.315 \ m[/tex]

Moment of inertia

[tex]I = \frac{1}{12} ML^2 + Md^2\\\\I = \frac{1}{12} (25)(0.91)^2 \ + \ (25)(0.315)^2\\\\I = 1.725 \ + \ 2.48\\\\I = 4.205 \ kgm^2[/tex]

Thus, the door's moment of inertia for rotation about a vertical axis inside the door, 14 cm from one edge is 4.205 kgm².
