When interpreting a job drawing, how can you distinguish a split pin from a solid pin based on conventional representation?
A split pin shows two legs with a visible gap
On a job drawing, standard machine parts are shown by fixed conventional symbols so anyone reading the drawing recognises them at a glance.
A split (cotter) pin is a length of half-round wire bent double, giving it two prongs or legs that are spread apart after fitting.
Its conventional representation therefore shows these two legs with a visible gap between them, which is what sets it apart from a plain solid pin drawn as a single straight body.
A centre-dot circle, zigzag lines or crossing lines are not the accepted convention for a split pin.
Hence, the answer is A split pin shows two legs with a visible gap.
