Engineering Mechanics Quiz

What is Engineering Mechanics?

• Study of chemical reactions

• Study of forces and their effects on bodies

• Study of weather patterns

• Study of living organisms

What is a Rigid Body?

• A body that is transparent

• A body that can change shape easily

• A body with constant distance between particles

• A body with no mass

What is the definition of Force?

• The action of one body on another trying to change its motion

• The measure of body's weight

• The resistance of a body to motion

• The interaction within a body

What is the Principle of Transmissibility of Force?

• Force can only act in one direction

• Force can be transmitted through air

• Force can be moved along its line of action without changing its effects

• Force can only be applied at one point

What is the Moment of a Force?

• The measure of force's speed

• The measure of force's tendency to rotate a body

• The measure of force's color

• The measure of force's temperature

What are Concurrent Forces?

• Forces that act in opposite directions

• Forces that act in the same direction

• Forces that intersect through a common point

• Forces that never meet

What is the Parallelogram Law of Addition of Forces?

• Forces subtract from each other to give resultant force represented by the diagonal of a parallelogram

• Forces add up to give resultant force represented by the diagonal of a parallelogram

• Forces add up in a circular motion to give resultant force represented by the diagonal of a parallelogram

• Forces add up in a equal and opposite direction to give resultant force represented by the diagonal of a parallelogram

What is the Resultant of a Force System?

• The sum of all forces acting on a body

• The average of all forces acting on a body

• The difference of all forces acting on a body

• The maximum force acting on a body

What is a Couple?

• A pair of forces with different magnitudes separated by a distance

• A pair of forces with the same magnitude separated by a distance

• A pair of forces with no displacement separated by a distance

• A pair of equal and opposite forces separated by a distance

What is the Resolution of Forces?

• Changing the direction of forces

• Doubling the magnitude of forces

• Combining forces into a single force

• Disintegrating a force into components
