How much force does it take to break an arrow?
There are 4.45 newtons per pound, so this gives us a force of 620 lbs. So. To launch a 400 grain arrow to a speed of 1200fps (give or take) with a 29inch draw length, you'd need a bow with a draw weight of at least 600lbs and probably more like 650.
How strong is an arrow?
The ballistic coefficient of an arrow isn't exactly constant, so the exact power it hits the target with could be anywhere from 40 to 50 foot-pounds of energy. An AR-15 will usually fire a 5.56mm bullet weighing 62gr, or 4 grams.
Is an arrow stronger than a bullet?
Arrows, on the other hand, have relatively lower velocities and kinetic energies than bullets. However, they are much heavier, longer, and more robust as projectiles when compared to bullets. Unlike bullets (depending on their design), arrows are usually not designed to deform on impact.
How far will an arrow go straight up?
Arrows have very low friction. But an arrow fired by a modern bow will be travelling at about 300–330fps, which means that if you shoot it straight up in the air it will travel about 6 seconds up and then come back down but when it lands it should be travelling at very close to the original velocity when it lands.
What does 400 mean on an arrow?
The numbers refer to the spine of the arrow. The different spines refer to the stiffness, a 400 spine arrow is generally for bows 40-60 lbs. 350 spine is for bows roughly 55 - 75 lbs, and a 500 spine arrow is for bows roughly 30 - 50 lbs.
How much force is needed to draw a bow?
As a general rule children that are 50 to 70 pounds can normally handle a draw weight under 15 pounds. Children between 70 and 100 pounds can normally handle a draw weight of 15 to 25 pounds.
What are energy arrows?
The energy is stored in the limbs in the form of potential energy; when the string is released the energy stored into the limbs is released, most of which is absorbed by the arrow. ... As the arrow travels downrange, the total energy diminishes due to air resistance and friction in the arrow materials as the arrow flexes.
What kind of force does an arrow have when released?
Archer’s Paradox. Another force acting on the arrow once it is released is vibration. This is a natural force that the arrow experiences, since a brief but large force has just been applied to it. This vibrating motion of the arrow is known as “fishtailing”.
How does the physics of archery affect the motion of the Arrow?
Physics Of Archery – Analysis Of Archer's Paradox Due to the relatively high force of the bow string acting on the arrow, it rapidly accelerates and a high-speed camera is required to capture the motion. Also, because this large force is acting in the direction of the arrow shaft, it begins to oscillate (fishtail) back and forth.
How big is the velocity of an arrow?
Even at an arrow mass of 520 grains, the velocity needs to be near 250 feet per second, yet a heavy arrow of 740 grains need only be traveling a little over 160 feet per second to reach this level of momentum (a velocity easily within the capability of most conventional and compound bows of only modest draw weight) .
How are acceleration and mass of an arrow related?
In archery, these forces (F) are directly related to the acceleration (a) and the mass (m) of the arrow. Large forces result in large acceleration, while large masses are very hard to accelerate or decelerate (think about pushing a car versus a bicycle on a level street).
