Module 1 - Statics of Particles Flashcards
a single force can be resolved to its?
rectangular components
examples of vector quantity
force, position, and moment
a physical quantity that has both magnitude (size) and direction
vector quantity
these are Analytical Methods used in addition of vector
law of sine and cosine
rectangular components
any physical quantity that
requires both a magnitude and a direction for its complete description
vector
what characterized the forces in a plane?
- point of application
- magnitude
- direction
examples of scalar quantity
length, mass, and time
it is used when we are given AAS, SSA, and ASA
sine rule
what is a single force called?
resultant
any positive or negative physical quantity that can be completely specified by its magnitude
scalar
When the resultant of all the forces acting on a particle is zero, the particle is in?
equilibrium
it is the line of action and the sense
of the force
direction
If the resultant force acting on a
particle is zero, the particle will
remain at rest (if originally at rest) or will move with constant speed in a straight line (if originally in motion)
newton’s first law
what are the ways to add vector forces?
- graphical way
- analytical way
it is used when we are given either SSS and SAS
cosine rule
a physical quantity that has only magnitude (size) but no direction
scalar quantity
these are Graphical Methods used in addition of vector
parallelogram law
triangular law
polygon rule for addition of vectors
methods used in addition of vector
graphical methods
analytical methods
This method for finding the resultant is known as the _________________________ for the addition of two forces.
parallelogram law
two vectors of unit magnitude, directed respectively along the positive x and y axes
unit vectors
