Question 1566

▼

How does reversing one force on a rod affect its motion?

It stops all motion
It causes vibration
It changes the mass of the rod
It changes the system from translational imbalance to rotational imbalance

Question 1567

▼

What is the significance of the midpoint in torque calculations for a symmetric rod?

It has no significance
It increases the force
It serves as a convenient point for calculating net torque due to symmetry
It stops rotation

Question 1568

▼

What is the net torque on a rod when two equal and opposite forces act perpendicularly at its ends in antiparallel fashion?

Zero
aF
2aF
F/a

Question 1569

▼

Why can't a particle be in rotational equilibrium in the usual sense?

Because it moves too fast
Because it has infinite mass
Because it is always accelerating
Because it has no dimensions and thus cannot rotate about an axis

Question 1570

▼

What type of equilibrium does a particle satisfy for mechanical equilibrium?

Rotational equilibrium only
Both translational and rotational equilibrium
Dynamic equilibrium only
Translational equilibrium only
