Note: The Mealy Machine requires one less state than the Moore Machine! This is possible because Mealy Machines make use of more information (i.e. inputs) than Moore Machines when computing the output. Having less states makes for an easier design because our truth tables, K-maps, and logic equations are generally less complex.
heavy-duty, made of spheroidal graphite cast iron, maintaining the rope into the grooves. A spring operated guide roll in the rope guide prevents slack in rope. The rope pulleys are made from spheroidal cast iron and the construction of large diameter pulleys ensures that the rope is retained in the pulley. Limit switches & buffers
CHARACTERIZATION OF WEAK ROPE THROUGH THE DESIGN AND CONSTRUCTION OF A PORTABLE TENSILE TESTING MACHINE BY GLENN MCGILLICUDDY B.S. Mechanical Engineering, University of New Hampshire, 2001 THESIS Submitted to the University of New Hampshire In partial fulfillment of The Requirement for the Degree of Master of Science In Ocean Engineering
Proper functioning of the machine implies the ability to do the required job dependably and well. Hence it is essential that the machine be designed to incorporate the best possible construction and methods of operation so as to get all the quality possible into the machine. One of the secrets of success in machinery design is to give the machine
Fatigue of Wire Rope Fig. 17–21does not preclude failure by fatigue or wear It does show long life if p/S u is less than 0.001. Substituting this ratio in Eq. (17–42), Dividing both sides of Eq. (17–42) by S u and solving for F, gives allowable fatigue tension, Factor of safety for fatigue is Shigley's Mechanical Engineering Design
This is the wire rope construction that is most widely used for general engineering purposes. Six (or eight strand) ropes (Fig. 1(b)) are manufactured in essentially two stages: wires are twisted together to form the strands (which have an equal lay length to allow different wire diameters to nest together), then six (or eight) strands are twisted together over a core to make the rope.

Rope makers had to be skilled artisans to produce quality ropes under these conditions. The entire rope making process was affected by the ability and experience of the rope maker. Although machines gradually replaced skilled rope makers, traditional techniques survived until after the Civil War. V. THE CRAFT: Rope was one of man's earliest tools.
