You are designing a flywheel to store large amounts of kinetic energy.
Which of the following uniform shapes will be the most effective for
storing the greatest amount of kinetic energy if all the objects have the
same mass and same angular velocity? - correc answer_ A thin walled
hollow cylinder of diameter D rotating about an axis perpendicular to
the plane of the circular face of its center
Four uniform objects having the same mass and diameter are released
simultaneously from rest at the same distance above the bottom of a
hill and roll down without slipping. The objects are a solid sphere, a
solid cylinder, a hollow cylinder, and a thin-walled hollow cylinder.
Which of these objects will be the first one to reach the bottom of the
hill? - correc answer_ The solid sphere

Which of these objects will be the last one to reach the bottom of the
hill? - correc answer_ The thin-walled hollow cylinder
What is the most accurate statement concerning the elastic modulus? -
correc answer_ Elastic modulus is a constant of proportionality that
relates stress to strain.
What is the most accurate statement concerning simple harmonic
motion (SHM)? - correc answer_ SHM describes the vibrational motion
of an object oscillating back and forth through an equilibrium position.
What is the most accurate statement concerning an object undergoing
simple harmonic motion (SHM)? - correc answer_ The object's velocity
is maximum as it passes the equilibrium position.
What is the most accurate statement concerning sound waves? - correc
answer_ Sound waves are longitudinal waves whose wave speed
depends on the transmitting medium.
