The pitcher's elbow is the catapult. It's the main reason why so many pitchers have to undergo Tommy John surgery, which is when the elbow's ulnar collateral ligament is reconstructed from other ligaments in the body.
cartilage
The joint, near where the tendon is attached to the bone, acts as the fulcrum.
Gravity pulls the projectile down towards the ground, affecting its trajectory. Air resistance acts against the forward motion of the projectile, slowing it down as it travels through the air. These forces must be accounted for when designing and using a catapult for accurate targeting.
joint committee
Cartilage is important in joint because it acts as a shock absorber.
If the muscle crosses a joint (most do), then the joint acts as a pivot.
There are different types of catapults. Simple ones can be called catapults or onagers. Other types of siege, like the trebuchet, is a tall and long ranged version of a catapult. There is also a type which acts like a large crossbow, which of the name varies.
Cartilage acts as a cushion at a joint by providing a smooth surface for the bones to move against without rubbing or causing friction. This helps to reduce wear and tear on the joint and provides shock absorption during movement.
Catapults work like third class levers. The base acts as the fulcrum on which the catapult arm pivots. Force is provided by rubber bands attached to the crossbar of the catapult. The rubber bands tighten when the arm is pulled back, so when the arm is released, it is propelled forward until it hits the crossbar. The object being launched is then propelled forward into the air.
Cartilage is important in joints because it acts as a shock absorber, reducing friction and providing cushioning during movement. This helps protect the bones within the joint from wear and tear.
biceps brachii
Synovial fluid is found in the joint capsule and acts as a lubricant for articulating surfaces.
