Mechanics Chapter 8 - Modelling Flashcards
1
Q
Particle assumptions
A
dimensions of the object are negligible, and rotational forces/air resistance can be ignored
2
Q
Rough surface assumptions
A
objects in contact with surface experience friction
3
Q
Smooth surface assumptions
A
objects in contact with surface do not experience friction
4
Q
Peg/Support assumptions
A
dimensionless and fixed
5
Q
Rod assumptions
A
one dimension is negligible, mass is concentrated along line, rigid
6
Q
Inextensible string assumptions
A
acceleration is the same in any connected objects
7
Q
Smooth/light pulley assumptions
A
no friction, pulley has no mass, tension the same in string either side of pulley
