A wheel with radious 75 cm is made of a hoop with mass 1.9 Kg and four rods with mass 0.7 Kg and length 75 cm. What is its moment of inertia when rotating around a perpendicular axis that goes through its center? (kg*m^2)
Respuestas a la pregunta
Inertia is the property that bodies possess to oppose a change in their state of rest or movement in which they find themselves.
r = 75 cm = 0.75 m
m1 = 1.9 Kg
Four rods with mass 0.7 Kg a
L = 75 cm.
What is its moment of inertia when rotating around a perpendicular axis that goes through its center? (Kg * m ^ 2)
I = R² (M + 4/3 * m)
I = (0.75 m) ² (1.9 kg + 4/3 × 0.7 kg)
I = 1.59 kg * m²

La inercia es la propiedad que posee los cuerpos de oponerse a un cambio de su estado de reposo o movimiento en que se encuentran.
r = 75 cm =0,75 m
m1 = 1.9 Kg
Cuatro barras con una masa de 0.7 Kg
L = 75 cm.
¿Cuál es su momento de inercia cuando gira alrededor de un eje perpendicular que atraviesa su centro? (Kg * m ^ 2)
I = R² (M + 4/3 *m)
I = (0,75 m)² (1,9 kg + 4/3 × 0,7 kg)
I = 1,59 kg *m²
