CSEC Technical Drawing · May/June 2007 · Paper 2 · Question 3

Figure 3 shows a crank OA of length 25 mm rotating about centre O, with a connecting link AB of length 110 mm constrained at end B to move along line XY.

Draw the locus of point P on link AB (where AP = 45 mm) as crank OA completes one full rotation in the direction of arrow 'F'.

This question uses a figure or table from the paper — you'll see it when you practise.
