A bow draw in archery is the method or technique of pulling back the bowstring [1] to store energy for the bow to shoot an arrow. The most common method [citation needed] in modern target archery is the Mediterranean draw, which has long been the usual method in European archery. Other methods include the pinch draw and the Mongolian or "thumb ...
Medieval European crossbows had a much smaller draw length than bows, so that for the same energy to be imparted to the projectile the crossbow had to have a much higher draw weight. A direct comparison between a fast hand-drawn replica crossbow and a longbow shows a 6:10 rate of shooting [92] or a 4:9 rate within 30 seconds and comparable weapons.
Thus, if other factors are equal, a standard Han dynasty crossbow with a ≈387-pound (176 kg) draw weight and a 20–21-inch (510–530 mm) powerstroke would have comparable levels of power to a medieval European crossbow with a 1,200-pound (540 kg) draw weight and a 6–7-inch (150–180 mm) powerstroke.

The Excalibur was designed as "clone" [1] of the Quad City Challenger II aircraft. The company took the basic Challenger design and incorporated many changes, including mounting the engine upright allowing larger propellers and the Rotax gearbox to be mounted, lengthening the tailboom and enlarging the tail vertical surface to increase stability, shortening the ailerons and replacing control ...
let-off (measure) – The difference between a compound bow's holding weight and draw weight. Expressed as a percentage of the draw weight; for example, a bow with a draw weight of 70 lb and holding weight of 14 lb would have 80% let-off. limb-driven rest (equipment) – A drop-away rest that is mechanically linked to one of a compound bow's limbs.
When the archer commences the draw, mechanical advantage is at its greatest and the bow limbs are only pre-stressed to the strung position; therefore drawing weight is at a minimum. However, the drawing weight rapidly increases because mechanical advantage reduces (consider the string is pulling more and more directly on the limbs) and stresses ...
GNAS recognizes three grades of arbalist, [14] Master Arbalist (scoring 780 or higher in three qualifying Crossbow Windsor Rounds) Arbalist 1st Class (scoring 630 or higher) and Arbalist 2nd Class (480). A Crossbow Windsor Round is shot on a 60 cm 10-zone face scoring 9,7,5,3,1; three ends at 40 yards, three at 50 yards and three at 60 yards.
The main armament of the Genoese crossbowmen was the crossbow, made in Genoa by the Balistrai Corporation. As well, the mercenaries were equipped with a dagger, a light metal helmet, a gorget, a hauberk and a large shield, called a pavese , which was used while reloading the crossbow. The usual team consisted of a crossbowman and two assistants ...
