Part B please QuestionThe two uniform thin discs shown in the figure rest on a horizontal plane and areconnected through frictionless pin-joints at A and B by a rigid light rod whichremains horizontal. The mass of disc A is 15 kg. and that of disc B is 25 kg. Thestatic coefficients of friction between the plane and discs A and B are, respectively,(,),= 0.2 and (u), = 0.55.At the instant shown, a counter-clockwise moment T = 125 Nm. is applied to discB. You are required to,(a) identify the type of ensuing motion of the discs,(b) draw the free-body, kinematic and kinetic diagrams of the discs,(c) assuming motion initiates with pure rolling, write down theappropriate kinematic and kinetic relationships with respect to asuitable global axes system, and(d) determine, in magnitude and direction, the angular accelerationsof the discs and force developed in the rod AB at the instant themoment T is applied.(e) Validate the pure rolling assumption in part(c) and if slipping isanticipated, explain with supporting arguments, whether one ofthe discs will first slip, or both discs will slip at the same time.You must clearly show details of the analysis that you have carried out usingrelationships in part (c) to arrive at subsequent results in a neat, logical way.0.45 m60⁰0.6 m30.45 m60°0.6 m

Free Body Diagram

The system of forces acting on a body tends to either rotate it or make the body undergo motion. In general, when an external agent exerts a force on a body, the body undergoes translational motion and rotational motion. The body has six degrees of freedom under the influence of that force. Here, three degrees of freedom are from the translational motion while the other three are from the rotation motion. However, sometimes the bodies are not allowed to undergo any motion and are fixed, under such conditions the body is said to be constrained.

A heavy cask (full of wine!) sits on an inclined plane. It is held in place by a rope that is attached to the cask and to a hook further up the inclined plane (at A). The rope comes off of the cask tangent to the cask. The mass of the cask is 40 kg, and the coefficient of static friction between the inclined plane and the cask is 0.25. What is the maximum value of θ just before the cask begins to slip? Also, what is the tension in the rope when slipping is impending?
