Pronunciation: [fˈʌlkɹəm] (IPA) 
The word "fulcrum" is spelled with a silent "c" which makes it a bit tricky to pronounce. The correct pronunciation is fʊlkrəm. The "f" and "l" sounds are straightforward, but the "u" is pronounced like "uh" and the "cr" sounds like "kr". The "u" and "c" together make an "ə" or "uh" sound. Fulcrums are important in physics as they are the point on which a lever pivots, allowing for the transfer of force.
A fulcrum is a fundamental mechanical device used to successfully execute various forms of leverage or rotation. It refers to the fixed point around which a lever pivots, providing support and enabling the lever to function effectively. The term "fulcrum" is derived from the Latin word "fulcire," meaning "to prop up" or "to support."
Typically, a fulcrum is a solid and immovable object positioned beneath, adjacent to, or incorporated within a lever, beam, or seesaw. It serves as the point of stability and balance, permitting the lever to move and transfer force efficiently. The placement of the fulcrum relative to the other components greatly affects the leverage achieved. It determines the ratio between the force exerted on one end of the lever and the resulting force applied on the other.
Physically, a fulcrum can take various forms, such as a rigid bar, a fixed point on a stable surface, or a specially designed component. It is crucial to ensure that the fulcrum is adequately strong and secured, as its stability directly impacts the entire lever's functionality.
The concept of fulcrum extends beyond mechanical systems, finding its application in other fields as well. Metaphorically, it can represent the central point or key element upon which something crucial or significant relies or revolves. In physics, the fulcrum exemplifies the principle that every action has an equal and opposite reaction, emphasizing the conservation of energy and the balanced nature of mechanical systems.
A prop or support; that by which any lever is sustained; in bot., a general name for several of the appendages of the stem or leaves, which serve for support or defence.

The word "fulcrum" is derived from the Latin word "fulcra" which means "prop" or "support". It is derived from the verb "fulcire", meaning "to prop up" or "to support". The Latin word itself can be traced back to the Proto-Indo-European root "*bhelg-" which means "to swell" or "to bulge". The concept of a fulcrum as a support or pivot point is reflected in its etymology, as it relates to providing support or balance.
