Part B As shown, a cam has a shape that is described by the function - 7o (2.00- cos ), where = 1.14 m. A slotted bar is attached to the origin and rotates in the horizontal plane with a constant angular velocity of 0.495 radians/s. The bar moves a roller having a mass of 15.0 kg along the cam's perimeter. A spring holds the roller in place; the spring's spring constant is 11.2 N/m. The friction in the system is negligible. When (= 105°, what are F and Fa, the magnitudes of the cylindrical components of the total force acting on the roller? Express your answers numerically in newtons to three significant figures separated by a comma. View Available Hint(a) FAX F.F 0.538,0.825 c ? N

Consider the disk and axle shown below. The axle has a constant angular velocity (in rad/s) in the inertial frame given by: A/N = 0.152 i. The disk has an angular velocity (in rad/s) in the axle frame given by: p/A 0.504 k . Calculate the magnitude of angular acceleration of the disk in the inertial frame (in rad/s?). N D

A wheel rotating with 16 rev/s is uniformly accelerated at 0.4 rad/s2 for 10 seconds. It then rotates with a uniform speed  for next 9 s. Then it is made to stop in next 15 s. Determine (i)maximum angular velocity; (ii) total angular displacement The velocity of the wheel at 10 seconds in rad/s is ? The angular displacement for the first case in rad is? The angular displacement for the second case in rad is? The maximum velocty in rad/s  is? The angular displacement for the last case in rad is? The total angular displacement in rad is?
