# What is Body: Definition and 1000 Discussions

Body art is art made on, with, or consisting of, the human body. The most common forms of body art are tattoos and body piercings. Other types include scarification, branding, subdermal implants, scalpelling, shaping (for example tight-lacing of corsets), full body tattoo and body painting.
Body art is also a sub-category of performance art, in which artists use or abuse their own body to make their particular statements.
More extreme body art can involve mutilation or pushing the body to its physical limits.
In more recent times, the body has become a subject of much broader discussion and treatment than can be reduced to body art in its common understanding. Important strategies that question the human body are: implants, body in symbiosis with the new technologies, virtual bodies, among others.

38. ### B How to calculate torque on a body falling freely through the sky?

if a body is pivoted at a point it is quite easy to calculate the torque as we know the axis of rotation. but, if a body is under free fall and we apply a force of F Newtons at a distance of x from its centre of mass , then how do we determine the axis of rotation?
39. ### I Why does a body at rest move if Gravity is not a force?

hello according to GR gravitational force is not a real force rather a space time curvature ok a body in motion follows a sort of invisible rails why doesn't a body at rest remain at rest, then ?
40. ### Wanting to study energy in the human body

Summary:: Looking for a certain degree program What kind of degree would be best if I really wanted to get into studying energy within and around the human body and interactions of it between electronic signals and things like that? I am really starting to believe that our understanding of...
41. ### Work done in moving a body up an incline

##W=mgh=100(\sin 37)2=-120J## Right answer! But the question is asking work done by the person. So again I wrote two eqns ##F_N\sin 53+F_D\sin 37-100=10.2a_y## ##F_N\cos 53-F_D\cos 37=-10.2a_x## I just need ##a_x## and ##a_y## to solve.
42. ### B Can I hold down more than my body weight on a 1 to 1 system?

Can you pull down/hold more weight than your body using your muscles? Imagine a 1 to 1. One side is suspended 190 pounds, the other is me, 175 pounds. Can i, using my muscles and standing on the ground, hold that suspended weight off the ground? I understand if i lock out my arms and...
43. ### I Rigid body physics (machine learning environment)

I guess that the reason that objects fall over is that there is nothing to hold it's center of mass. So what I want to do is to work out how fast in Delta intervals it would rotate and fall over.
44. ### I Hypothetical Velocity Faster Than C: Exploring Relativity

I know it isn't possible for any mass/massless body to have velocity more than the speed of light in vacuum but what if it was done hypothetically? As far as I know length and time of an object undergo a transformation so that the laws of physics remain same between observers at rest and...
45. ### A question about resistance in the human body

Back in grade 10..,.( Oh my that was awhile back 😀 ) our electronics teacher passed around a multimeter and everyone measured their resistance ( a lead held in each hand, Fluke was set on infinite ). All in the class measured between 700K and 800K approx. All except me that is. I measured 1.4M...
46. ### Body forces in static equilibrium (FEM issue)

Hi, I have an issue with understanding the body forces in the context of FEM simulations. I am using freefem to do the simulations. So I took a simple unit cube, fixed the displacements at side ##x=0## and prescribed a displacement ##u_x = 0.025## at ##x=1##. If required, the entire script is...
47. ### B Question about a simple free body diagram

In this diagram, if the system begins by being held static, and then at time ##T## release of all components occurs, at all times ##>T##, until vertical movement stops upon vertical block ##m## making contact with the Normal Force at the base of block ##M##, will the lateral acceleration of...
48. ### COVID COVID-19 in Brain (and rest of body) up to 8 months (so far)

It's a pre-print from a bunch of researchers at the NIH. https://assets.researchsquare.com/files/rs-1139035/v1_covered.pdf?c=1640020576 No wonder Long Covid exists! ?:)
49. ### B Exploring the History of Calculating Solar System Body SGPs

does anyone have a good reference on the history of calculating the standard gravity parameters of solar system bodies? My guess is a rough estimate of Jupiter's SGP can be gained from observing the motion of its moons, in which case the first estimates could have been made soon after Newtonian...
50. ### I Usage of First Order Elastic Constants in Soft Body Equations

Hi, I have some soft body equations that require first order elasticity constants. Just trying to figure out the proper indexing. From Finite Elements of Nonlinear Continua by J.T. Oden, the elastic constants I am trying to obtain are the first order, circled below: My particular constitutive...
