What is the moment arm?

• The moment arm is the angle between two vectors.

• The moment arm is the force applied to an object.

• The moment arm is the distance between two points on a lever.

• The moment arm is the perpendicular distance between the line of action of a force and the axis of rotation or point of rotation.

Which of the following factors affect the moment of an object?

• Mass of the object and time of application of force

• Magnitude of force and distance from pivot point

• Shape of the object and material of the pivot point

• Color of the object and temperature of the environment

What is the moment of a force equal to?

• The moment of a force is equal to the square of the magnitude of the force multiplied by the perpendicular distance from the point of rotation to the line of action of the force.

• The moment of a force is equal to the product of the magnitude of the force and the perpendicular distance from the point of rotation to the line of action of the force.

• The moment of a force is equal to the sum of the magnitude of the force and the perpendicular distance from the point of rotation to the line of action of the force.

• The moment of a force is equal to the magnitude of the force divided by the perpendicular distance from the point of rotation to the line of action of the force.

What is the principle of moments?

• The principle of moments is the law stating that the sum of the clockwise moments about any point must be equal to the sum of the anticlockwise moments about the same point.

• The principle of moments is the law stating that the sum of the clockwise moments about any point must be equal to zero.

• The principle of moments is the law stating that the sum of the anticlockwise moments about any point must be equal to the sum of the clockwise moments about the same point.

• The principle of moments is the law stating that the sum of the clockwise moments about any point must be equal to the sum of the anticlockwise moments about a different point.

What is the moment of a couple?

• The moment of a couple is the product of one of the forces in the couple and the parallel distance between the forces.

• The moment of a couple is the result of dividing one of the forces in the couple by the perpendicular distance between the forces.

• The moment of a couple is the sum of the forces in the couple.

• The moment of a couple is the product of one of the forces in the couple and the perpendicular distance between the forces.

How can you increase the moment of an object?

• By increasing the mass or increasing the distance from the axis of rotation.

• By decreasing the speed or increasing the distance from the axis of rotation.

• By decreasing the mass or decreasing the distance from the axis of rotation.

• By increasing the speed or decreasing the distance from the axis of rotation.
