Term
 Bodies
Definition
 real solids, gases, or liquids
Term
 Particle
Definition
 It is a real body with no size or shape (ignoring size, shape) not a point, only representation
Term
 Rigid Body
Definition
 Real body with defined size and shape but changes in size/shape ignored
Term
 Forces
Definition
 are either external and internal to the body
Term
 False
Definition
 Internal forces are present in particles T or F
Term
 Concurrent forces
Definition
 Lines of action of all forces intersect at one single point
Term
 Non Concurrent Forces
Definition
 act at different points on an object and result in a net turning moment, or torque, acting on the object.
Term
 False
Definition
 Non concurrent forces act on a particle T or F
Term
 True
Definition
 All forces acting on a particle are concurrent T or F
Term
 True
Definition
 Forces acting on a particle are non parallel T or F
Term
 True
Definition
 The lines of action of all parallel forces must be separated by a finite distance T or F
Term
 No
Definition
 Can a particle be subjected to parallel forces?
Term
 False
Definition
 The Principle of Transmissibility can be applied to a particle T or F
Term
 The Principle of Transmissibility
Definition
 States that push and pull are the same. If a force acting at a given point of the rigid body is replaced by a force of the same mag. and dir. , but acting at a different point.
Term
 Space Diagram
Definition
 not drawn in scale but in proportion
Term
 Free Body Diagram
Definition
 Forces acting on a rigid body or bodies, shows where the forces are acting and you can see all the LOA
Term
 Force Diagram
Definition
 It is a diagram showing forces arranged in a certain order for the sole purpose to construct a triangle to get resultant or to compare two forces to the third one
Term
 True
Definition
 Equilibrium of a particle all forces must be concurrent T or F
Term
 Theta y
Definition
 Angle given vector makes with the y-axis in a plane containing the vector and the +y-axis between 0 and 180
Term
 Phi
Definition
 The angle the projection makes with the x-axis in a plane containing the projection of the vector and the +x-axis between 0 and 180
Term
 False
Definition
 (Theta)x, (Theta)y, (Theta)z are called directional cosines T or F
Term
 1
Definition
 The sum of the squares of the directional cosines is equal to
