Static Equilibrium Concepts

Which of the following is a condition for static equilibrium?

• Sum of all forces is zero and sum of all torques is non-zero

• Sum of all forces is non-zero and sum of all torques is zero

• Sum of all forces is zero and sum of all torques is positive

• Sum of all forces is zero and sum of all torques is zero

What is the relationship between torque and leverage?

• Torque is inversely proportional to leverage.

• Torque has no relationship with leverage.

• Torque is equal to leverage.

• Torque is directly proportional to leverage.

How does the center of mass affect an object's stability?

• The center of mass increases the object's tendency to tip over

• The center of mass makes the object float in mid-air

• The center of mass has no impact on stability

• The center of mass affects stability by lowering the object's tendency to tip over.

What role does static friction play in maintaining equilibrium?

• Static friction accelerates the object when an external force is applied.

• Static friction has no impact on maintaining equilibrium.

• Static friction causes the object to rotate uncontrollably.

• Static friction prevents the object from sliding or moving when an external force is applied.

In static equilibrium, the sum of all forces acting on an object is equal to?

• 10 N

• 0 N

• 9 N

• 5 N

A force that is applied at a distance from the pivot point creates what?

• Force

• Acceleration

• Torque

• Velocity

Why is it important to consider the center of mass in determining stability?

• Considering the center of mass is important in determining stability because it helps predict how an object will behave under external forces.

• Stability is solely determined by the shape of an object

• The center of mass has no impact on stability

• Considering the center of mass is irrelevant for stability

What happens to an object in static equilibrium if the sum of torques is not zero?

• The object will remain in static equilibrium.

• The object will disappear.

• The object will start rotating or moving.

• The object will change color.

How does increasing static friction affect an object's stability?

• Increasing static friction improves an object's stability.

• Increasing static friction causes an object to become more unstable.

• Increasing static friction decreases an object's stability.

• Increasing static friction has no effect on an object's stability.

What is the significance of the torque being zero in static equilibrium?

• The significance of the torque being zero in static equilibrium is that there is no net rotational force causing the object to rotate, indicating that the object is in a stable position.

• It indicates that the object is accelerating

• There is a net rotational force causing the object to rotate

• The object is in an unstable position
