Answer:
71.42857 kgm²
1311.81946 kg
5.082 rad/s
Explanation:
F = Force = 200 N
R = Radius = 0.33 m
= Angular acceleration is 0.924 rad/s²
Moment of inertia is given by
The moment of inertia of the wheel is 71.42857 kgm²
Moment of inertia of a solid cylindrical wheel is given by

Answer:
The first frequency of audible sound in the speed sound is
f = 662 Hz
Explanation:
vs = 344 m/s
x = 52 cm * 1 / 100m = 0.52m
The wave length is the distance between the peak and peak so
d = 2x
d = 2*0.52 m
d = 1.04 m
So the frequency in the speed velocity is
f = 1 / T
f = vs / x = 344 m/s / 0.52m
f ≅ 662 Hz
