An unusually small crossbow bolt with a tapered "waist" shaft section and rear skirt compared to a 1 euro cent coin A bolt or quarrel is a dart -like projectile used by crossbows . [ 1 ] The word quarrel is from the Old French quarrel (> French carreau ) "square thing", [ 2 ] specialized use as quarrel d'arcbaleste (> carreau d'arbalète ...
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.
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 ...
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.

Since the arbalest was much larger than earlier crossbows, and because of the greater tensile strength of steel, it had a greater force. The greater draw weight was offset by a shorter draw length, which limited the total potential energy that could be transferred into the crossbow bolt. A skilled arbalestier (arbalester) could loose two bolts ...
The M982 Excalibur was fielded as a guided shell that effectively hit within 6 m (20 ft) of a target, but the Army developed the XM1156 as a cheaper alternative. The PGK fuse can be screwed onto existing M549A1 and M795 projectiles, be fired from M109A6 Paladin and M777A2 Howitzer artillery systems, and hits within 50 m (160 ft) of the target ...
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.
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.
