Justification of design 01 with respect to datum

OBJECTIVES SCORE GIVEN WITH DATUM REFERENCE JUSTIFICATION
SAFETY - There is high chance of detaching wheels from the track
USER FRIENDLY 0 The model is easy to use as datum
USE OF STANDARD PARTS - All parts are replaceable
COST + The model costs less as compared to datum

Justification of design 2 with respect to datum

OBJECTIVES SCORE GIVEN WITH DATUM REFERENCE JUSTIFICATION
SAFETY - There is high risk of breaking of window
