Draw the following objects and identify the center of mass in each.
Give five examples of objects in which
rotational and translational motion are both present.
What is the moment of inertia?
What does this statement mean?: "The moment
of inertia is the rotational analog of mass?"
What units are moment of inertia measured
How many formulas are there for calculating
the moment of inertia?
Copy Table 8-1 on p285 *completely* in
the space below.
What is translational equilibrium?
What is the symbol for translational equilibrium?
What is rotational equilibrium?
What is the symbol for rotational equilibrium?
A uniform bridge 20.0 m long and weighing
4.00 x 10^5 N is supported by two pillars located 3.00 m from each end.
If a 1.96 x 10^4 N car is parked 8.00 m from one end of the bridge, how
much force does each pillar exert?
Draw the figure 8-9 on p 289. At
which of the seven positions A through G should the supporting pivot be
located to produce:
-a) a net positive torque
-b) a net negative torque
-c) no rotation
