# Essay On Hooke's Law

1477 Words 6 Pages
A bow is basically a two-armed spring that stores mechanical “potential energy” once the string is drawn and pulls back the limbs. After you recoil the cord, you utilize your muscles to exert a force on the string that bends the limbs backward. The quantity of force that your fingers exert on the string once you’ve to force it all the means back is named the “draw weight.” The elastic or spring energy is currently “potential energy” that may be reborn into launching associate arrow after you unleash the string. Hooke’s Law states that the draw weight is proportional to the draw length. The bigger quantity that you simply deform the limbs by pull them back more in your draw length, the additional you increase the force that successively will …show more content…
Also, as a result of this massive force is acting in the direction of the arrow shaft, it begins to oscillate (fishtail) back and forth. this is often the natural vibration the arrow experiences once subjected to a quick however giant force. It 's just like hit one thing with a hammer and it moving as a result. The force engaged on the arrow is capable the draw force because the archer pulls the string back to the discharge position (at full draw). This force will be within the vary of 30-50 lbs., that is incredibly giant compared to the mass of the arrow, that is why it accelerates thus apace (due to Newton 's second law, F = …show more content…
Drag; conjointly apprehend as resistance, is that the force that resists the movement of a solid object through a fluid. It’s created by friction forces, that act parallels to the object’s surface. Thus, by transferring the momentum from the arrow to the air, the arrow is stalled. There area unit 2 styles of drag that act on the associate arrow: shear drag because the arrow flies through the air, mechanical energy is spent to maneuver the fluid out of the means, therefore, the arrow could pass. this can lead to friction. The shear drag is proportional to the rate of the arrow within the air, however, opposite in direction. Fd = - bv. kind drag is because the arrow flies through the air, the shear drag can produce eddies. These eddies, that area unit the whirling of the air within the reverse current, can kind turbulent wakes, therefore, leading to kind drag. kind drag is proportional to the sq. of the arrows. Fd = -
