HELICAL SPRINGS: Helical springs are mechanical devices designed to
store energy by compression, extension, or torsion and return an equivalent
amount of energy when released. Drawings seldom show a true
representation of the helical shape. Draw helical springs on machine
drawings with detailed or schematic (single-line) representation.
Figure 4-39 shows detailed and single-line representations of helical springs.
