A bucket of water with total mass 23 kg is attached to a rope, which in turn is wound around a 0.050-m radius cylinder at the top of a well. A crank with a turning radius of 0.25 m is attached to the end of the cylinder and the moment of inertia of cylinder and crank is 0.12 kg∙m^2. If the bucket is raised to the top of the well and released, what is the acceleration of the bucket as it falls toward the bottom of the well？ _______m/s^2. (Assume rope's mass is negligible, that cylinder turns on frictionless bearings and that g = 9.8 m/s^2.)

In the mechanism showed in following figure, driving link 1 rotates in constant angular velocity
by driving torque . Frictional circles of revolute pairs are labelled in the figure. Frictional angle
.
is working resistance. Mass and inertia force of each link are not calculated. Try to label the position and direction of total reaction force of each kinematical pair and write force balance equation for link 2 and draw vector polygon to resolve this equation.
