Modelling Assumptions June 2024 Exam
Questions and Answers 100% Pass
particle - Answer>>dimensions of the object are negligible.
dimension - Answer>>e.g. width, depth and height.
a line has one dimension, a square has two dimensions, and a
cube has three dimensions.
negligible - Answer>>insignificant; not worth considering.
particle - assumptions (2) - Answer>>⇒object's mass is
concentrated at a single point.
⇒rotational forces & air resistance can be ignored.
rod - Answer>>all dimensions but one are negligible, e.g. a pole
or a beam.
rod - assumptions (3) - Answer>>⇒mass is concentrated along
a line.
⇒no thickness.
⇒rigid (doesn't bend or buckle.)
buckle - Answer>>give way under pressure or strain.
lamina - Answer>>object with area but negligible thickness, e.g.
a sheet of paper.
lamina - assumption (1) - Answer>>⇒mass is distributed across
a flat surface.
