ROTATIONAL MOTION

What is the condition for a body to be in complete static equilibrium?

• Only net force zero
• Only net torque zero
• Body is at rest
• Both net force and net torque are zero

How does the concept of CG apply to real-world structures like bridges?

• It is irrelevant
• It makes them longer
• It helps in ensuring stability and balanced load distribution
• It reduces material cost

What would be the reaction at K₂ if the load were at G?

• 98.00 N
• 54.88 N
• 43.12 N
• 49.00 N

Why are knife edges used instead of flat supports in Example 6.8?

• To increase weight
• To measure time
• To reduce friction and ensure vertical reaction forces
• To make it look scientific

What is the distance from P to G in Example 6.8?

• 10 cm
• 15 cm
• 5 cm
• 25 cm
