Making a speed mouse trap car involves extracting the most energy you can from the mousetrap spring in a short distance. The lever arm needs to be shorter than the distance car's because the shorter the arm is, the quicker the spring will snap, and thus more torque gets extracted from the spring.
The gun-powered mouse trap proved inferior to spring-powered mousetraps descending from William C. Hooker's 1894 patent. However, the 1882 patent has continued to draw interest–including efforts to reconstruct a version of it–due to its unconventional design. [4]
If the mouse attempts to take the bait, the coin is displaced and the glass traps the mouse. [14] Another method of live trapping, the bucket trap , is to make a half-oval shaped tunnel with a toilet paper roll, put bait on one end of the roll, place the roll on a counter or table with the baited end sticking out over the edge, and put a deep ...
A V-twin engine, also called a V2 engine, is a two-cylinder piston engine where the cylinders are arranged in a V configuration and share a common crankshaft. The V-twin is widely associated with motorcycles, primarily installed longitudinally, though also transversely. They are also used in a variety of other land, air, and marine vehicles, as ...

If a man can write a better book, preach a better sermon or make a better mouse-trap than his neighbors, though he builds his house in the woods, the world will make a beaten path to his door. Researchers believe it likely that Emerson used a modified version of the theme from his journal in a lecture given at some point after 1855, with the ...
Mousetrap (anti-Submarine Projector, Marks 20 and 22) was an anti-submarine rocket launcher used mainly during World War II by the United States Navy [1] and Coast Guard. [2] Its development began in 1941 as a replacement for Hedgehog anti-submarine mortar .
The acardiac twin is a parasitic twin that fails to properly develop a heart, and therefore generally does not develop the upper structures of the body. The parasitic twin, little more than a torso with or without legs, receives its blood supply from the host twin by means of an umbilical cord-like structure (which often only has two blood vessels, instead of three), much like a fetus in fetu ...
