Can an arrow be supersonic?

Recall that the speed of sound is only 343 m/s, which means a supersonic arrow is just barely possible.

What speed is a pound of draw weight?

Looking at the data for all four test bows, the minimum speed change per pound of draw weight is 1.9 fps and the maximum is 2.4 fps.

How much strength do you need to pull a bow?

Some compound bows can be adjusted over a 50-pound range, such as 15 to 65 pounds, while others offer a smaller range of poundage adjustment such as 10 pounds.. Every person has an ideal draw weight. Some archers easily pull 30 pounds, and others can pull over 70 pounds.

How do I determine my bow speed?

Arrow speed is measured in feet per second, or fps. The higher the number, the faster the bow. A bow rated at 300 fps is faster than a bow rated at 290 fps. Bow companies list “ATA” or “IBO” next to their speed ratings.

How do I determine my bow draw weight?

To determine your draw length, you must measure the distance between the string/nock point of the arrow and the point where the arrow touches the arrow rest (the ‘pivot point’) when a bow is fully drawn and at anchor. An additional 1.5-1.75 inches must then be added to this distance to determine your draw length.

How can I increase my arrow speed?

The farther you draw the bow the more energy you store in it. With more potential energy in the drawn bow, there will be more kinetic energy in the released arrow – more arrow speed. As you lengthen your draw you must go to a longer and stiffer arrow for the same maximum draw weight.

How hard is it to pull back a 40 pound bow?

The draw weight is basically, “How strong do I need to be in order to pull this thing back?” For a recurve bow, it’s measured by pulling back to 28 inches. So for a 40 lb bow, it means that it takes 40 lbs of force to pull back the string 28 inches for a recurve.

How much draw weight do you need to fire an arrow?

If you have a 30 lb draw weight on your bow, then you can only fire so far. The draw weight, arrow weight (measured in grains), and draw length will all define the speed of your arrow, but draw weight is the most important. You can have a low draw weight around 25-35 lbs, but still have a high draw range of about 30” or so.

How much does draw weight matter in archery?

The draw weight, arrow weight (measured in grains), and draw length will all define the speed of your arrow, but draw weight is the most important. You can have a low draw weight around 25-35 lbs, but still have a high draw range of about 30” or so.

How much force does it take to draw a 70lb bow?

Theoretically, “drawing” a bow that measures 70lbs requires the same amount of force as it would to lift a 70lb weight from the ground, obviously the movements would be different but the resistance would be the same. The draw weight is influenced by a few factors, but the most notable is the stiffness or rigidity of the limbs.

How much does an arrow shaft weigh?

Using GPI calculations, a light shaft weighs 5 to 6 grains per inch, a midweight shaft weighs 7 to 9 grains per inch, and a heavy shaft weighs 10 or more grains per inch. A light arrow has a finished GPP of 5 to 6.5 grains for each pound of draw weight. A midweight arrow weighs between 6.5 and 8 grains. Heavy arrows weigh over 8 grains.
