True/False:  Indicate whether the following statement is true or false.  If the statement is true, justify your reasoning.  If the statement is false, correct the statement to make it true or justify why it is false. LO 18a: When analyzing a rigid body that is translating or rotating, the units for kinetic energy are different because the units of velocity and angular velocity are different.

Problem:  Use the figure below to answer the following questions.  Assume the assembly rotates about the z-axis at 12 rad/s while the disk rotates about the y-axis at 10 rad/s. The mass of the disk is 0.5 slugs. LO 21a & 21b: What is the mass moment of inertia of the disk about the y- and the z-axes?  Show your work. Value Solution Units [sol] [units] [sol2] [units2]

Problem: Use the figure below to answer the following questions.  A horizontal force, P = 100 N,  is applied to the reel shown below.  The 300 kg reel has a radius of gyration of k = 0.265 m.  Assume the rollers at A and B have negligible mass and roll freely.  LO 19a: If the reel is initially rotating at 5 rad/s, what is the angular momentum at t = 6 s? Show your work. Solution Units [sol] [units]

True/False:  Indicate whether the following statement is true or false.  If the statement is true, justify your reasoning.  If the statement is false, correct the statement to make it true or justify why it is false. LO 19b: When considering conservation of momentum for a rigid body, it is possible for momentum to be conserved in one direction, but not another.
