A = bow riser/grip, B = median plane of the bow, C = arrow aiming line and trajectory Arrow flexing both towards and away from the bow handle. The archer's paradox is the phenomenon of an arrow traveling in the direction it is pointed at full draw, when it seems that the arrow would have to pass through the starting position it was in before ...
Archer's paradox: An archer must, in order to hit his target, not aim directly at it, but slightly to the side. Not to be confused with the arrow paradox. Not to be confused with the arrow paradox. Arrow paradox : If we divide time into discrete 0-duration slices, no motion is happening in each of them, so taking them all as a whole, motion is ...
In anatomy, flexor is a muscle that contracts to perform flexion (from the Latin verb flectere, to bend), [1] a movement that decreases the angle between the bones converging at a joint. For example, one's elbow joint flexes when one brings their hand closer to the shoulder , thus decreasing the angle between the upper arm and the forearm .
archer's paradox (effect) – The effect produced by an arrow flexing as it leaves the bow; archery (practice) – The practice of using a bow to shoot arrows; arm guard (equipment) – A protective strap or sheath for an archer's forearm (a.k.a. bracer) arrow (equipment) – A shafted projectile that is shot with a bow
Lombard's paradox describes a paradoxical muscular contraction in humans. When rising to stand from a sitting or squatting position, both the hamstrings and quadriceps contract at the same time, despite them being antagonists to each other. The rectus femoris biarticular muscle acting over the hip has a smaller hip moment arm than the ...
The anterior compartment of the arm is also known as the flexor compartment of the arm as its main action is that of flexion. The anterior compartment is one of the two anatomic compartments of the upper arm, the other being the posterior compartment. The compartment contains three muscles; the biceps brachii, the brachialis and the ...
Archer Aviation Inc. (NYSE:ACHR) shares are trading lower on Thursday. The company announced a new exclusive partnership with Anduril Industries to develop a hybrid Vertical Take-Off and Landing ...
Extension usually results in straightening of the bones or body surfaces involved. For example, extension is produced by extending the flexed (bent) elbow. Straightening of the arm would require extension at the elbow joint. If the head is tilted all the way back, the neck is said to be extended.
