The circular disk of mass m and radius r, is rolling through the bottom of the circular path of radius R. If the disk has an angular velocity determine the force N exerted by the path on the disk.
At the instant shown, link CD rotates with an angular velocity of W = 9.0 rad/s. If it is
subjected to a couple moment M= 320 N-m, determine the magnitude of the
vertical reaction force developed on pin D. The block has a mass of 50 kg and center
of mass at G. Neglect the mass of links AB and CD. (Hint, since the mass of link AB
or CD is negligible, the external force or moment acting on it sums up to 0.) Please
pay attention: the numbers may change since they are randomized. Your answer
must include 1 place after the decimal point, and proper unit. Take g = 9.81 m/s².

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.
