b. Construction. Propeller shafts may be solid or
a. Purpose. The power, having been transmitted
tubular. The torsional stress In a shaft varies from zero
through an angle by means of a universal Joint, is next
at the axis to a maximum at the outside. Because the
carried along the power train by a device known as a
center of the shaft resists only a small portion of the load,
propeller, or drive, shaft. Propeller shaft is the most
hollow shafts are used wherever practicable. A solid

shaft is somewhat stronger than a hollow shaft of the
amphibious vehicles, both terms are used: propeller
same diameter,
shaft, to indicate the device that transmits power to the
propeller; and drive shaft, to Indicate that which transmits
