Therefore reciprocating/cyclic devices tend to be less efficient than rotary devices; this is not a firm rule however, as some reciprocating devices include means to store energy through the non-productive part of the cycle while some rotary devices are less efficient for other reasons.
The distribution of the impacts showed that 90% of impacts from the rotary were less than 190 g and 90% of impacts from the slapper and sway were less than 250 g.
The rotary was less precise than the old cylindrical variety, but it was cheaper to manufacture and good enough for North America's coarse grass.
A biomimetic Carangiform robotic fish provides great benefits with flexible maneuverability, high propulsion efficiency and less noisy considering classical rotary underwater vehicles.
They make a pleasant whirring noise, have no exhaust, are easy to store, will not fling rocks or other objects at walls and observers and cost less than a power rotary mower.
Buyers in the United States were notified of the full-purchase-price offer in late August after Mazda determined that the RX-8's rotary engines produced less horsepower than the company's earlier estimate, a spokesman, Jeremy Barnes, said.
In most of seamless tube making industries, the useful life of mandrels for rotary forging is less than 350 perforation events; though in some cases, the tool may last longer than 1000 perforations.
The reciprocating single-file instruments resulted in less apical extrusion than the rotary full-sequence systems.
The filtrate was concentrated under reduced pressure at less than 40°C using a rotary evaporator (Buchi Rotavapor R-200/205, Switzerland) to obtain a crude residue.
Overall, knife grid cutting energy was much less than energy values published for rotary equipment.
In 1967 Matsuda helped Mazda introduce the Cosmo 110S, which had a rotary engine that was less fuel-efficient than other models.
