ROTATIONAL MOTION MCQ Quiz: GKFix - Bridge of Knowledge - Page 305

Question 1521

▼

How does the point of application of a force influence rotational motion?

It changes the mass
It affects only speed
It determines the lever arm and hence the torque produced
It has no effect

Question 1522

▼

What is the net effect when two equal and opposite forces act along the same line on a rigid body?

It rotates
It translates
The body remains in complete equilibrium
It oscillates

Question 1523

▼

Why do equal and opposite forces at the ends of a rod not always cancel rotational effects?

Because forces are unequal
Because the rod is asymmetric
Because they may act in the same rotational sense about the center
Because gravity interferes

Question 1524

▼

What is the motion of a freely suspended rod when a couple acts on it?

It moves linearly
It remains completely at rest
It vibrates
It rotates about its center of mass

Question 1525

▼

What determines whether a force system produces rotation in a rigid body?

The color of the object
The temperature
The presence of a net torque due to unbalanced moments
The time of day
