M3.5.2 - Simple cases of equilibrium of rigid

Simple cases of equilibrium of rigid To include bodies. (i) suspension of a body from a fixed point, (ii) a rigid body placed on a horizontal or inclined plane.

Use simple cases of equilibrium of rigid to connect the rule to the data and decision in the question.

This matters because simple cases of equilibrium of rigid determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply simple cases of equilibrium of rigid to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: Simple cases of equilibrium of rigid is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
