One of the simple machines

Usage examples of pulley.

Springs, alembics, coils of copper tubing, buckled sheets of metal, gear systems both rack-and-pinion and epicyclic, pendulums, levers, cams, cranks, differentials, bearings, pulleys, assorted tools, and stone jars containing alkahest and corrosive substances crowded every horizontal surface.

The skiff dropped down the side of the cog, the lines whirring through the pulleys.

Without this advanced system of cable and pulley, diplodocus could have activated neither her neck nor her tail, and she could not have survived.

The muscle innervated passes through a ring of connective tissue so that it resembles a small pulley, whence the name.

It suddenly touched bottom, but a big wave made the boat heel, and Javel, junior, who was in the bows directing the lowering of the net, staggered, and his arm was caught in the rope which the shock had slipped from the pulley for an instant.

I shake my traveling risers loose from my full-body harness, slide my hands over the crowded gear sling that we call a rack, find the two-bearing pulley by feel, clip it on to the riser ring with a carabiner, run a Munter hitch into a second carabiner as a friction-brake backup to the pulley brake, find my best offset-D carabiner and use it to clip the pulley flanges together around the cable, and then run my safety line through the first two carabiners while tying a short prusik sling onto the rope, finally clipping that on to my chest harness below the risers.

Aenea once told me that there used to be fixed carbon-carbon lines running the length of the slideway, and the sledders had clipped on to them much as we would a cableway or rappel line, using a special low-friction clip ring similar to the cable pulley to keep from losing speed.

Daryll and Mathias had set up a small quintain, a man-shaped dummy on a series of ropes and pulleys, so that it would move.

Further progress in mechanics was made by Cardan who explained the lever and pulley, and by Simon Stevin who first demonstrated the resolution of forces.

To use its pulley and winch for clearing the boulder, to check the bluff in case he was still up there, for whatever reason, Teasle must have radioed for it almost immediately.

The tellurium is comprised of brass or wooden balls representing the Sun, Earth, and Moon with associated gears, arms, and pulleys, and is used to demonstrate the mechanics of eclipses and of the seasons.

And if you were inclined to tinker with the vehicleby removing sound deadeners, undercoating, sway bars and interior wheel wells and playing around with the pulleys and cylinder heads, for instanceyou could goose the effective hp up to 450.

Dogras, Rajputs, Jats, Baluchis, Garhwalis clutched at the little pulleys over their cots, pulled themselves up with painful efforts, and saluted.
