ROTATIONAL MOTION

How does the mass of the suspended load affect the reaction forces?

• It decreases reactions
• It has no effect
• It makes reactions equal
• It increases both reactions and creates imbalance

What is the direction of the moment caused by R₂ about G?

• Anticlockwise
• Clockwise
• Zero
• Oscillating

Why is G chosen as the pivot for moment calculation in Example 6.8?

• Because it is the end
• To include all forces
• Because it is marked
• To eliminate the torque due to the rod's own weight

What is the role of gravity in the experimental determination of CG?

• It pushes sideways
• It disappears
• It provides the force that creates a restoring torque until alignment
• It heats the object

How does the experimental method in Fig. 6.25 confirm the CG location?

• By weighing each part
• By measuring thickness
• By averaging shapes
• By intersection of vertical lines from different suspension points
