Engineering Mechanics: Statics & Dynamics Chapters 1-11
Mechanics - ANSWER✔ � -A branch of the
physical sciences that is concerned with the state of rest or motion bodies that are subjected to the
action of forces.
Rigid-Body Mechanics:
Statics - ANSWER✔ � -Deals with the equilibrium of bodies, that is, those that are either at rest or
move with a constant velocity.
Rigid-Body Mechanics:
Dynamics - ANSWER✔ � -Is concerned with the accelerated motion of bodies.
Particle - ANSWER✔ � -Has mass, but a size that can be neglected.
Rigid-body - ANSWER✔ � -A combination of a large number of particles in which all the particles
remain at a fixed distance from one another, both before and after applying a load.
Concentrated force - ANSWER✔ � -represents the effect of a loading which is assumed to act at a point
on a body.
Rectangle Coordinate System - ANSWER✔ � -Is said to be right-handed if the thumb of the right hand
points in the direction of the positive z acts when the right-hand fingers are curled about the axis and
directed from the positive x towards the positive y axis.
Position Vector R - ANSWER✔ � -A fixed vector which locates a point in space relative to another point.
