ROTATIONAL MOTION

What would be the effect of doubling the mass of the rod in Example 6.8?

• No change
• Only R₁ increases
• Both reactions would increase, but ratio may change
• Reactions halve

Why is the rod considered a rigid body in Example 6.8?

• It is flexible
• It changes length
• Because it does not deform under the applied loads
• It is made of metal

How does the principle of moments apply in Example 6.8?

• By adding all forces
• By measuring length
• By ignoring gravity
• By setting the sum of clockwise and anticlockwise moments to zero

In Example 6.8, what is the role of point P?

• It is the CG
• It is a knife edge
• It is the midpoint
• It is the point where the external load is applied

What is the main advantage of using the suspension method for irregular shapes?

• It is faster
• It requires advanced tools
• It does not require mathematical calculation or symmetry
• It works only for metals
