Static Definition and 1000 Threads

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.

    Volume of Static Solid Using Cross-Sectional Area (Integration)

    Ok, so doing this one direction, with the range of x (0 to 2), I get the top minus the bottom equation of: ## y = 8 - x^3 ## Then, since it's squares, this would make it ##y^2##. So, integrating gives: ## \int_{0}^{2} (8-x^3)^2 = 82.3 ## That seems to be correct. However, I want to make...

    Static vs Kinetic Friction on an Unbanked Ramp

    I used kinetic friction and did mgμ_k=mv^2/r. However, the solution is mgμ_s=mv^2/r. I am confused on why we consider static friction and not kinetic friction, thanks!

    Direction of static friction between a vehicle and circular dome

    So the only problem I am having is determining the direction of static friction.

Would it be...

    Static Friction Required to Keep the System from Moving (Two Boxes)

    Ok, logically, it must be that the static friction force of block A equal to the force of gravity on block B, so mass of block A is: m_A * 9.8 * 0.30 = m_B * 9.8 m_A * 2.94 = 2 * 9.8 m_A * 2.94 = 19.6 m_A \approx 6.7 kg. However, when I look at block A individually, there is one thing...

    Consider a block sitting on top of a table. When we push the block rightwards, static friction opposes its motion by acting leftwards on the block. By Newton's 3rd Law, static friction should act rightwards on the table. There is now a net rightwards force on the table. Why doesn't the table...

    Force of the wall against the ladder is from static friction?

    A ladder is leaning against a frictionless wall and the floor. The force F of the wall against the ladder is what is opposing static friction f at the floor. I don't understand how the force F causes the ladder to slide to the left on the floor unless opposed by friction force f. See picture below.
