Exercise 3 solution

Working load = 900 / 5 = 180 units.

Whipping: success looks like tight, even turns with no gaps, a whipping about as long as the rope is wide, the twine pulled under and trimmed, and no unravelling when you tug the end. Common faults: loose turns (pull tighter as you wind), pulling the wrong end of the twine, and leaving the whipping too short.
