Mix Terms Flashcards
by teacher
The state of balance of a body where the resultant of all forces and couples acting on it is zero.
EQUILIBRIUM
The combined effect of all forces acting on a body, which must equal zero for equilibrium.
RESULTANT
A sketch representing a body and all the forces acting on it, useful for analyzing rigid body dynamics.
FREE BODY DIAGRAM
The force exerted perpendicular to a surface by an object in contact with that surface.
NORMAL FORCE
The force exerted parallel to a surface in contact, opposing the motion of an object.
FRICTION FORCE
A type of support that allows rotation and can only exert a normal force, analogous to a frictionless surface.
ROLLER SUPPORT
A support that provides both horizontal and vertical reactions, allowing for rotation while resisting translation
PIN/HINGE SUPPORT
A support that can exert horizontal and vertical reactions as well as a moment, restricting both translation and rotation.
BUILT-IN SUPPORT / FIXED SUPPORT/ CANTILEVER SUPPORT
To compute the resultant of the general force system, use
PYTHAGOREAN THEOREM
If ΣF=0 and ΣM≠0, then the resultant is a
COUPLE
A type of beam in which the supports are fixed support and a roller or pin.
PROPPED CANTILEVER BEAM
Cantilever beam is a type of statically ___ beam.
DETERMINATE
It is composed of straight members connected by rigid or pin connections to form a stable configuration.
FRAME
Give 1 most common situation where the pin reactions of the frame are not equal and opposite.
EXTERNAL LOADS ARE APPLIED AT THE PIN / THREE MEMBERS ARE CONNECTED AT THE PIN
A structure that is made of straight, slender bars that are joined together to form a pattern of triangles.
