angular kinetics Flashcards
1
Q
what will a force acting through the centre of rotation cause?
A
translation (movement in position)
2
Q
what will a force that isn’t acting through the centre of rotation cause?
A
translation and rotation
3
Q
what will a couple (two equal and opposite parallel forces acting on opposite sides of the axis) cause?
A
only rotation
4
Q
what does the magnitude of a moment depend on?
A
the magnitude of the force, the perpendicular distance of the moment arm, and the direction of the applied force
5
Q
what is equilibrium?
A
a state of balanced forces and moments
