Extra Mechanical Theory

Question 1

Rigid bodies

Answer 1

Bodies that do not perform any mechanical change when a forced in applied on themselves.

Question 2

Statics in Mechanics

Answer 2

Deals with the equilibrium of bodies subjected (sometido) to forces

Question 3

Properties of force

Answer 3

• magnitud is the quantitative effect
• direction which includes a line of force
• point of application, on rigid bodies, the point of application of a force doesn’t matter as long as it’s following its line of force

Question 4

Types of forces

Answer 4

• Concentrated Force: doesn’t exist really but it implies force at a single point
• volume force: distributed over the volume or portion of it
• Area force: occurs in regions where two bodies are in contact

Question 5

Classification of forces

Answer 5

Active forces: physically prescribed forces (attained through mathematical processing) in a mechanical system

Reaction forces: generated if the freedom of movement of a body is constrained. Usually visualized through cutting free or isolation, which means separating the force from its geometrical constraints
