ROTATIONAL MOTION

How is the distance PG calculated in Example 6.8?

• By adding AP and AG
• By measuring directly
• By subtracting AK₁ from AG
• By subtracting AP from AG

What is the value of g used in Example 6.8?

• 10 m/s²
• 9.8 m/s²
• 8.9 m/s²
• 9.5 m/s²

Why doesn't the weight of the rod contribute to the moment about G?

• It is too small
• It acts horizontally
• It is balanced by the supports
• Because its line of action passes through G

• Translational equilibrium
• Linear equilibrium
• Rotational equilibrium
• Harmonic equilibrium

What type of equilibrium requires the sum of forces to be zero?

• Rotational equilibrium
• Dynamic equilibrium
• Static stability
