Total questions: 15
Worksheet time: 8mins
Varignon’s Theorem states that the moment of a force about a point equals the moment of:
Only the horizontal component
Only the vertical component
The sum of its components
The largest component
Varignon’s Theorem is applied in:
Moment calculations
Density measurements
Friction analysis
Stress analysis
The moment of a force becomes zero when its line of action:
Is horizontal
Is vertical
Passes through the pivot
Is broken into components
Varignon’s theorem helps simplify moment problems by using:
Force components
Mass
Velocity
Pressure
The vector operation most closely related to Varignon’s theorem is the:
Dot product
Cross product
Scalar division
Vector projection
The moment of a force increases when the force becomes more:
Parallel to the pivot
Perpendicular to the lever arm
Vertical
Horizontal
According to Varignon, components produce the same moment as the:
Full force
Horizontal axis
Vertical axis
Pivot point
Using force components in moment calculations is useful because they are:
Independent of direction
Easier to visualize
Perpendicular to each other
Both B and C
Varignon’s Theorem applies to:
Only 2D forces
Only 3D forces
Any force in any dimension
Only forces along a lever arm
Breaking a force into components does NOT change its:
Angle
Line of action
Moment
Direction
Which statement best describes Varignon’s Theorem?
Components reduce the moment
Components increase the moment
Components create the same moment as the original force
Components eliminate the moment
Varignon’s Theorem is used most frequently in:
Thermodynamics
Statics
Fluid mechanics
Circuits
The moment of a force is also known as:
Torque
Stress
Strain
Pressure
Varignon’s Theorem allows engineers to:
Avoid decomposition
Use either components or full force
Ignore force direction
Cancel all moments
Varignon’s theorem relies on the idea that forces can be:
Multiplied
Subtracted
Added vectorially
Ignored
