Understanding Torque and Equilibrium

What is the formula for calculating torque?

• Torque (τ) = Distance (r) × sin(θ)

• Torque (τ) = Force (F) × Distance (r)

• Torque (τ) = Force (F) / Distance (r)

• Torque (τ) = Force (F) + Distance (r)

If a force of 10 N is applied at a distance of 2 m from the pivot, what is the torque?

• 25 N·m

• 15 N·m

• 20 N·m

• 5 N·m

What is the condition for static equilibrium?

• Only the sum of torques must be zero.

• The object must be in motion to achieve equilibrium.

• The sum of forces and the sum of torques must both be zero.

• The sum of forces must be greater than the sum of torques.

If an object is in static equilibrium, what can be said about the sum of the forces acting on it?

• The sum of the forces is equal to the object's weight.

• The sum of the forces acting on it is zero.

• The sum of the forces is greater than zero.

• The sum of the forces is dependent on the object's mass.

What happens to the torque if the distance from the pivot is doubled while keeping the force constant?

• The torque remains the same.

• The torque decreases by half.

• The torque doubles.

• The torque quadruples.

Which of the following statements is true about torque?

• Torque is measured in units of mass.

• Torque depends on both the force applied and the distance from the pivot point.

• Torque is the same regardless of the distance from the pivot point.

• Torque is only dependent on the force applied.

What is the unit of torque in the International System of Units (SI)?

• joule (J)

• kilogram-meter (kg·m)

• watt (W)

• newton-meter (N·m)

If a seesaw is balanced, what can be said about the moments on either side of the pivot?

• The moments on either side are zero.

• The moments on one side are greater than the other.

• The moments on either side of the pivot are unequal.

• The moments on either side of the pivot are equal.

What is the effect of increasing the angle of force application on torque?

• Increasing the angle of force application has no effect on torque.

• Torque decreases continuously with any increase in angle of force application.

• Torque is maximized at 180 degrees of force application.

• Increasing the angle of force application increases torque up to 90 degrees, after which it decreases.

In a system in equilibrium, what is the relationship between clockwise and counterclockwise moments?

• Clockwise moments are greater than counterclockwise moments.

• The clockwise moments equal the counterclockwise moments.

• The sum of clockwise moments is twice that of counterclockwise moments.

• Counterclockwise moments are always zero in equilibrium.
