1
New cards

Give the modelling assumptions of a PEG

Dimensionless,

Fixed in position

2
New cards

Give the modelling assumptions of a BEAD

Moves freely,

Tension is the same on either side

Assumptions of a particle (mass concentrated at single point, rotational forces and air resistance can be ignored)

3
New cards

Give the modelling assumptions of a INEXTENSIBLE STRING

Acceleration is the same for both objects connected by an inextensible string

4
New cards

Give the modelling assumptions of a LIGHT STRING

The tension is the same throughout the string

5
New cards

Give the modelling assumptions of a ROD

Rigid,

No thickness,

Mass concentrated along a line

6
New cards

Give the modelling assumptions of a PARTICLE

Mass concentrated at a single point,

Rotational forces + air resistance can be ignored
