cable
strong rope made of metal used in structures

centriod
geometrical center of an area

compression force
body subjected to a push

concurrent force systems
all forces applied at the same point/ action lines having the same intersection

crosssectional area
exposing a surface or shape by cutting through a 90 degree angle from the axis

direction
direction of a vector is defined by the angle between a reference point and the arrow's line of direction

fixed support
prevents translation or rotation in a beam

flange
broad ridge, connected at a right angle, that's used to strengthen a structure

free body diagram
shows all external forces acting on a body

guesset
plate or bracket used to strengthen an angle

joint
connection of points of members of a truss

magnitude
absolute value of a number

member
straight pieces of a truss

method of joints
analysis of trusses that contructs free body diagrams of each joint & determins forces acting on that joint by considering the equilibrium of the joint pin

moment
turning effect of a force

moment of inertia
mathmatical property of a crosssection that is concerned with surface area & how that area is distributed about a centroidial axis

Newton's 1st law
things at rest stay at rest, things in motion stay in motion unless acted upon by another force

Newton's 2nd law
change of motion of a body is proportional to the net force applied

Newton's 3rd law
for every action there is an equal and opposite reaction

pinned support
prevents translation in any direction

planar truss
lies on a single plane. often used to support roofs & bridges

resultant force
result of a system of force is the vector sum of all forces

roller support
only prevents a beam from translating in 1 direction

scalar
physical quiantity that has magnitude only

sense
direction of the vector realtive to its path & indicated by the location of the arrow

simple truss
composed of triangles

static quilibrium
no motion or continuous motion

statically inderminate
a body that is overconstrained such that there are no more unkown supports than there are equations of static equilibrium

structure
make up of interdependant parts in a definite pattern & organization

tension force
body subjected to a pull

vector quality
quantity with both magnitude & direction
