3. The 300-kg gear has a radius of gyration about its center of mass O of ko = 400 mm. If the wheel
is subjected to a couple moment of M= 300 N-m, determine its angular velocity 6 s after it starts
from rest and no slipping occurs. Also determine the friction force that the ground applies to the
wheel. Solve the problem using Impulse and Momentum.

Fast.
The 30-kg wheel has a radius of gyration about its center O of ko = 240 mm, and
radius r = 0.5 m. When the wheel is subjected to the constant force F = 388 N,
applied to the wheel's center axle at an angle = 6°, it starts rolling from rest.
Determine the total angular impulse L (in N•m.s) about the wheel's IC after 3.7
seconds if the wheel has been rolling without slipping. Please pay attention: the
numbers may change since they are randomized. Your answer must include 1 place
after the decimal point. Take g = 9.81 m/s².
