Module 14: Plane Motion (Force and Acceleration) Flashcards
(15 cards)
in this type of motion, the acceleration π is identically equal to zero
centroidal rotation
this is relations between the forces acting on a rigid body, the shape and mass of the body, and the motion produced
kinetics of rigid bodies
it is concerned with the exact location of the points of application of the forces
kinetics of rigid bodies
The motion of the mass center πΊ of the body with respect to the newtonian frame of reference ππ₯π¦π§
translational equation of motion
this principle states that the external forces acting on a rigid body are equivalent to the effective forces of the various particles forming the body.
dβAlembertβs Principle
The motion of the body relative to the centroidal frame of
reference πΊπ₯βπ¦βπ§β
rotational equation of motion
in this type of motion, the effective forces of the body reduce to the couple πΌΜ πΌ
centroidal rotation
The external forces acting on a body in ______________________ are equivalent to a couple of moment πΌΜ
πΌ
centroidal rotation
in this type of motion, the angular acceleration of the body is identically equal to zero
translation
They will be restricted to the __________________ of rigid bodies, i.e., to a motion in which each particle of the body remains at a constant distance from a fixed reference plane
plane motion
Two systems of forces which are equipollent (have the same resultant and the same moment resultant), are also?
equivalent
Except for _____________________________________, which applies to the most general case of the motion of a rigid body, the results derived will be limited in two ways
Equations of Motion for a Rigid Body
they have exactly the same effect on a given rigid body
equipollent systems of forces
these are made up of large numbers of particles
rigid bodies
it is concerned with the motion of the body as a whole and the motion of the body about its mass center
kinetics of rigid bodies
