PS CA6(3)

What is the primary condition for an object to remain in static equilibrium?

• Zero acceleration

• Zero net force and zero net moment

• Balanced velocity

• Constant pressure

In a Free Body Diagram (FBD), what does each arrow represent?

• Weight only

• Velocity direction

• A force acting on the object

• Work done on the system

What is the purpose of calculating moments in statics?

• To measure velocity changes

• To analyze rotational equilibrium

• To determine energy transfer

• To calculate pressure variations

What does the term "moment" in statics refer to?

• A change in motion

• The rotational effect of a force

• The speed of an object

• The tension in a rope

What is the equation for calculating a moment about a point?

• Force × Distance from the point

• Force ÷ Distance from the point

• Mass × Acceleration

• Velocity × Time

Which of the following best describes a distributed load?

• A single concentrated force

• A load applied over a surface or length

• A force acting in one direction only

• A load that varies in magnitude

In statics, the center of gravity is:

• The highest point on an object

• The point where the object's weight is concentrated

• The point of maximum force

• The point of minimum force

Which force acts perpendicular to a surface in contact with an object?

• Normal force

• Frictional force

• Applied force

• Gravitational force

What does the term "couple" mean in statics?

• Two opposing forces creating a rotation

• Two objects with balanced mass

• A point where forces cancel out

• Two forces in the same direction

When resolving forces, what is used to separate a force into components?

• Vector diagrams

• FBD analysis

• Equilibrium equations

• Force triangles
