What is Static: Definition and 1000 Discussions

Static is a fictional superhero appearing in American comic books published by DC Comics. The character was created by Milestone Comics founders Dwayne McDuffie, Denys Cowan, Michael Davis, and Derek T. Dingle. Static's first appearance was made in Static #1 (June 1993) in the Modern Age of Comic Books, written by McDuffie and Robert L. Washington III, and illustrated by John Paul Leon. Virgil Ovid Hawkins is a member of a fictional subspecies of humans with superhuman abilities known as metahumans. Not born with his powers, Hawkins' abilities develop after an incident exposes him to a radioactive chemical. This event renders him capable of electromagnetic control and generation.
The character drew much inspiration and was in fact designed to represent a modern-era Spider-Man archetype. After the closing of Milestone Comics, Static was incorporated into the DC Universe and became a member of the Teen Titans. A common misconception is that Hawkins is the son of fellow DC Comics superhero Black Lightning, who debuted much earlier and possesses electrical abilities. Black Lightning addresses the coincidence once in a Justice League narrative.Static has made numerous appearances in other forms of media. The character has been featured in various animated series, including Static Shock, a version of the storyline made slightly more suitable for a younger audience, as well as animated films and video games.

    What determines the direction of static friction forces?

    My understanding of static friction is that it is a resistive force in response to an applied force. I recently read the following example. A rope of uniform density, length L, is fastened to a plane with incline angle “theta” along its length. The question asks for the tension at the top of...

    Fatigue life hand calculations based on static FEA results

    What is the relationship between torque, linear force, and rolling resistance?

    Say that I have a round object on a table and it is still. If I apply a force and it doesn't move the resistive force is rolling resistance rather than a frictional force right? Now I must be able to apply forces in different amounts until it exceeds a boundary for the object to move similar to...
