Questions
The moment of inertia of an angular wheel shown in figure is 3200 . If the inner radius is 5 cm and the outer radius is 20 cm, and the wheel
is acted upon by the forces shown, then the angular acceleration of the wheel is
detailed solution
Correct option is C
τ = Iα ⇒ 10×20100+9×20100-12×20100 = 3200α⇒α = 10-3 rad/s2Talk to our academic expert!
