A car is moving on a curved horizontal road of radius 100 m with a speed of 20 m/s, The rotating masses of the engine have an angular speed of 100 rad/s in clockwise direction when viewed from the front of the car. The combined moment of inertia of the rotating masses is 10 kg-m². The magnitude of the gyroscopic moment in (N-m) is __________.
-
- 200 N-m
- 195 N-m
- 185 N-m
- 100 N-m
Correct Option: A
R = 100m, V = 200 m/sec,
| ωp = | = 0.2 rad/sec | R |
ωp = 100 rad/sec
I = 10 kg-m²
Gyroscopic moment = Iωsωp
= 10 × 0.2 × 100
= 200 N-m
