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 ...
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 ...
The Skåne lockbow was an early form of crossbow from Skåne or Scania, then a province of Denmark. (It has been part of southern Sweden since 1658.) An example was discovered in 1941 in Sweden dating from the 16th century, but seems to be similar to earlier models. The lockbow was used throughout northern Europe between ca. 900-1600 CE.
Estimates for the draw of these bows varies considerably. Before the recovery of the Mary Rose, Count M. Mildmay Stayner, Recorder of the British Long Bow Society, estimated the bows of the Medieval period drew 90–110 pounds-force (400–490 newtons), maximum, and W. F. Paterson, Chairman of the Society of Archer-Antiquaries, believed the weapon had a supreme draw weight of only 80–90 lb f ...
The medieval shortbow was technically identical with the classical era bows, having a range of approximately 91 m (299 ft). It was the primary ranged weapon of the battlefield through the early medieval period. Around the tenth century the crossbow was introduced in Europe. Crossbows generally had a longer range, greater accuracy and more ...
Nelson shares her Apple Watch stats: ‘For that 20-minute low-impact indoor walking workout, I burned 186 calories, and my average heart was 145bpm.
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.
