Cards in this set: Term Abutment Definition End support of bridge superstructure Term Arch Bridge Definition Bridge with two abutments, and with an arch shaped structure in the middle which supports the weight of the bridge Term Beam Bridge Definition A bridge consisting of horizontal beams supported by verticle posts Term Cable Stayed Bridge Definition A bridge which consists of any number of towers which have cables that attach to the road to support it Term Compression Definition Forcing two objects together which causes stress on a point of the object Term Equilibrium Definition The point in time when forces cancel eachother Term Force Definition An act of pushing or pulling Term Forces Definition The things which are doing the forcing Term Free Body Diagram Definition A pictorial representation often used by physicists and engineers to analyze the forces acting on a free body Term Friction Force Definition The resistance encountered when one body is moved in contact with another Term Impending Motion Definition Determine the direction of frictino based on the direction of impending slippage Term Mass Definition The amount of matter in an object Term Moments Definition A turing force produced by an object acting at a distance Term Newton's Laws Definition 3 physical laws which provide relationships between the forces acting on a body and the motion of the body Term Resultant Definition A single force that produces the same result that all forces would if acting together Term Scalar Quantity Definition A quantity that has no direction associated with it Term Suspension Bridge Definition A bridge that has a roadway supported by cables that are anchored at both ends Term Tension Definition A stress that produces an elongation of an elastic physical body Term Vector Quantity Definition A quantity that has direction and magnitude associated with it Term Weight Definition The vertical force exerted by a mass as a result of gravity Term Newton's First Law of Motion Definition Every objedt in a state of uniform motino tends to remain in that state of motion unless an external force is applied to it Term Newton's Second Law of Motion Definition the relationship between an object's mass m, its acceleration a, and the applied force F is F=ma. Acceleration and force are vectors (as indicated by their symbols being desplayed in slant bold font); in this law the direction of the force vector is the same as the direction of the acceleration vector Term Newton's Third Law of Motion Definition For eevery action there is an equal and opposite reaction
