What is Slider: Definition and 58 Discussions

The red-eared slider (Trachemys scripta elegans), also known as the red-eared terrapin, red-eared slider turtle, red-eared turtle, slider turtle, and water slider turtle, is a semiaquatic turtle belonging to the family Emydidae. It is a subspecies of the pond slider. It is the most popular pet turtle in the United States and is also popular as a pet across the rest of the world, and is the most invasive turtle. Because of this, it is the most commonly traded species of turtle in the world.Red-eared sliders are native to the Southern United States and northern Mexico, but have become established in other places because of pet releases, and have become an invasive species in many areas where they outcompete native species. The red-eared slider is included in the list of the world's 100 most invasive species published by the International Union for the Conservation of Nature.

    Building a better crankshaft (crank and slider)

    I am trying to build a dual input (double input) crankshaft, out of Lego. All the tutorials online use flywheels, but I want a strong high quality crankshaft that doesn't rely on flywheels. The crankshaft is for a 1 cylinder or sinusoidal linear type input. This video demonstrates the flaw of...

    Forces applied by a slot on a slider

    What forces are exerted by the slot on the slider? You have a normal force since it's inside it, and that's the only force that I can imagine. But then? I think about the pseudo-forces since it's on a rotating reference frame (centrifugal force, Coriolis force, Euler force), but those forces are...
