1.3.1 Turning Forces

• A turning force depends only on the magnitude of the force applied.

  False
• Increasing the distance from the pivot decreases the turning effect.

  False
• A turning force, also called a moment, depends on the force magnitude and the distance from the pivot
• A turning force, also known as a moment, causes rotation around a fixed point
• The formula for calculating moments is: Moment = Force × Distance from pivot
• The newton-meter represents the product of force in newtons and distance in meters.


  True
• What is the formula for calculating moments?

  Moment = Force × Distance
• Applying the force closer to the pivot point will result in a greater moment.

  False
• A force of 10 Newtons is applied 5 meters from a pivot point. What is the moment?

  50 N⋅m
• In equilibrium, the clockwise moments must equal the anticlockwise moments.
• What is the equilibrium condition for a door being pushed open?

  It is not in equilibrium
• A turning force, also known as a moment, is the measure of force required to cause rotation around a pivot point.
• A moment is also known as a turning force and depends on the magnitude of the force and the distance from the pivot.
• A greater force applied closer to the pivot results in a larger moment.

  False
• The moment of a force is constant regardless of the distance from the pivot.

  False
• A force of 20 N applied 3 meters from the pivot results in a moment of 60 N⋅m.


  True
• Match the factors with their importance in calculating moments:

  Force magnitude ↔️ Higher force = more turning effect

  Distance from pivot ↔️ Larger distance = more turning effect
• A force of 10 N applied 2 meters from the pivot results in a moment of 10 N⋅m.

  False
• The moment depends on two key factors: force magnitude and distance from the pivot
• The SI unit for moments is the newton-meter, abbreviated as N⋅m
• The principle of moments states that for an object in equilibrium, the sum of the moments around a pivot point must be zero.


  True
• What is the equilibrium condition for a see-saw with equal weights on each end?

  Clockwise = Anticlockwise moments
• The principle of moments can be used to solve equilibrium problems.
