Diagnostic Test - Statics

A rigid body is defined as an object that:

• Can be compressed or stretched

• Has negligible mass

• Does not deform under load

• Is made of steel

Which branch of mechanics studies bodies at rest under forces?

• Dynamics

• Kinematics

• Statics

• Thermodynamics

A free-body diagram (FBD) shows:

• All the parts of a system

• Internal and external forces acting on a body

• Motion paths of objects

• Energy levels in a body

Which of the following is a scalar quantity?

• Force

• Acceleration

• Mass

• Velocity

Two equal and opposite forces acting along the same line will:

• Move the object

• Cause rotation

• Cancel each other out

• Accelerate the object

The tendency of a force to rotate a body about a point is called:

• Power

• Moment

• Friction

• Tension

Which tool is most useful in solving statics problems?

• Multimeter

• Bunsen burner

• Free-body diagram

• Venn diagram

What condition ensures equilibrium in a particle?

• Acceleration is zero

• Velocity is maximum

• Sum of all forces is zero

• Mass is constant

Which of the following is not required in analyzing a 2D force system?

• Direction of forces

• Magnitude of forces

• Force vectors

• Color of the object

Newton’s First Law is most applicable in statics because:

• It explains rotational inertia

• It states that a body remains at rest if no net force acts

• It applies only to particles

• It defines gravitational force
