English version of the given question is as follows:
A homogenous solid wheel wrapped around a rope and the end of the rope is pulled with a force of 10N. If the mass of 4kg and 15 cm radius, the moment of inertia and the wheel acceleration are ...
Given :
F=10Nm=4kg
radius=r=15cm=0.15m
Moment of inertia =I=?
wheel acceleration =a=?
I=1/2 mr²
=(1/2 )4x( 0.15)²
=(1/2)x4x(0.0225)
=(1/2)x0.09
=0.045 kg m²
As we know that ∑ T=I.α
Fxr=I.α
10x0.15=0.045xα
α=10x0.15/0.045
=1.5/0.045
=33.3 rad/s2
