TEXTBOOK:        CHAPTER 13, Section 13.1 to 13.4, pages 273 - 282.  
                    CHAPTER 12, pages 245 - 265 (omit Sections 12.4 and 12.5).

OBJECTIVES:

• Determine whether a body is in static equilibrium under the action of known torques arising from known forces.

• State the two conditions necessary for mechanical equilibrium of a rigid body. 

• Draw a free-body diagram of an object and apply the two conditions of equilibrium to calculate an unknown force acting on an object, given adequate information about known forces and distances.

• Describe in detail the analogy between fixed-axis rotation and straight-line translation.

• Determine the angular acceleration with which a rigid body is accelerated about a fixed axis when subjected to a specified external torque or force.

• Apply conservation of energy to problems of fixed-axis rotation.

• Analyze problems involving strings and massive pulleys.

• Write down, justify, and apply the relation between linear and angular velocity, or between linear and angular acceleration, for a body of circular cross-section that rolls without slipping along a fixed plane, and determine the velocity and acceleration of an arbitrary point on such a body. 

• Apply the equations of translational and rotational motion simultaneously in analyzing rolling with slipping.

• Calculate the total kinetic energy of a body that is undergoing both translational and rotational motion, and apply energy conservation in analyzing such motion. 

• Calculate the torque of a specified force about an arbitrary origin. 

• Calculate the angular momentum vector for a moving particle. 

• Calculate the angular momentum vector for a rotating rigid body in simple cases where this vector lies parallel to the angular velocity vector.  

• Recognize the conditions under which the law of conservation of angular momentum is applicable and relate this law to one- and two-particle systems such as satellite orbits or the Bohr atom.  

• State the relation between net external torque and angular momentum, and identify situations in which angular momentum is conserved.  

• Analyze problems in which the moment of inertia of a body is changed as it rotates freely about a fixed axis.  

• Analyze a collision between a moving particle and a rigid body that can rotate about a fixed axis or about its center of mass.
