a rotor rotating about a fixed axis through its mass center, the rotor has a mass of 60 kg, radius of gyration of 70 mm, and angular acceleration of 9 rad/s2. determine the moment the fixed axis.



Answer :

Given

60 kg of mass, 70 mm or 0.07 meters of gyroscopic radius, and 9 rad/sec2 of angular acceleration

Utilized concept

Inertia, It is an object's resistance to any change in motion. The amount of inertia is directly related to an object's mass; in fact, as we frequently observe, the heavier an object is, the harder it is to change its direction of motion.

The moment of inertia must be identified. EM = I > I > MK2

I stands for inertia mass moment.

I = 60 kg/m2 M = I = 0.216 kg/m2 = 11 kg/m2 M = 2.376 nm

Answer:

Explanation:

Given:

m = 60 kg

R = 70 mm = 0.070 m

ε = 9 rad/s²

__________________

M - ?

The moment:

M = J·ε = m·R²·ε

M = 60·0.070²·9 ≈ 2.65 N·m
