Engineering Mechanics Flashcards
A BRANCH OF SCIENCE THAT DEALS WITH
THE BEHAVIOR OF A RIGID BODY WHEN THE
BODY IS AT REST OR IN MOTION
ENGINEERING MECHANICS
A BODY THAT DOES NOT DEFORM UNDER
LOAD
Rigid body
THE DISTANCE BETWEEN ANY 2 POINTS ON REMAINS CONSTANT
REGARDLESS OF EXTERNAL FORCES EXERTED
ON IT
Rigid body
THE STUDY OF EXTERNAL
EFFECTS OF FORCES ON A
RIGID BODY WHEN IT IS AT REST
AND REMAINS AT REST BEFORE
AND AFTER THE APPLICATION
OF FORCES
Statics
DEALS WITH THE STUDY
OF
EXTERNAL
FORCES
APPLIED ON A BODY
INDUCING ANY MOTION
Dynamics
THE
CAUSE
OF
CHANGE IN THE STATE
OF MOTION OF A BODY
A VECTOR QUANTITY
Force
A
QUANTITY
THAT
ONLY
HAS
A
MAGNITUDE
Scalar
A QUANTITY THAT HAS BOTH MAGNITUDE
AND DIRECTION
Vector
THE MEASUREMENT OF
THE EXTERNAL FORCES
APPLIED TO BODIES
Load
SERIES OF CONCENTRATED LOADS
WITH UNIFORM MAGNITUDE
Uniform load
SERIES OF CONCENTRATED LOADS
WITH VARYING MAGNITUDE
Varying line load
FORCES ACTING IN
THE SAME DIRECTION
BUT
DO
NOT
CONVERGE
AT
A
COMMON POINT
Parallel force
FORCES
ACTING
ON A SINGLE PLANE
Coplanar force
FORCES CONVERGING
AT A COMMON POINT
Concurrent force
REPRESENTATIVE FORCE
OF
THE
CUMMULATIVE
EFFECTS OF FORCES
Resultant force
