Hey, I wonder what class your doing this for, but there are a few ways I can think of from the top of my head.  \n\n- Conjoin paper clips\n- Roll and Fold paper to create bones\n- And/or Use toothpicks\n\nYou can even use all three in the same project. \n\nCheers.

use aluminum foil shape it up.. then for the final touch super glue it

My guess would be to take a piece of paper and fringe the bottom. Like, cut it into little sections but don't cut them completely off. That's the only way I know to do it.

1- Cub : use a squared sheet, cut 4 squares with length side = 1/3 the length side of the sheet from every corner of the sheet. bend to form the cub.\n2- Cuboid : Use a rectangle sheet, cut 4 squares with the same length side ( the height of the cuboid ) from every corner of the sheet. bend to form the cuboid. \n3- Pyramid : Use a uniform polygon sheet, let the no. of sides is n and its center m, cut one or more triangles of vertex m and its base is one sides of the polygon, bend to form the pyramid\n4- Use a circular sector sheet.

well, you tie a knot then fold each of the strings from each side in half then tie a knot with those folded pieces.

Tear a piece of paper up into ten pieces.  Write down an option on each and then fold them up.  Now, mix them up a bit and then draw one out.  Do whatever option you draw.  Have Fun!!!

draw FBDs of the 2 blocks independently\nbe careful\nfind the accelrations of the  2 blocks using CONSTRAINT relations\nand comes ur answer\n\ndon't wait for the solution\nit lessens ur thinking power n creativity\n\nif it's still problematic, consult ur lecturer\n\nconcentrate on ur studies \nur still a college guy

lines, polylines, blocks, circles etc... look in the help files if you have the software\n\nhttp://www.we-r-here.com/cad/tutorials/index.htm

Actually the only way it would be possible is if you use Elliptic or Riemannian geometry, and would require a manifold.  A representation of such a construct would be similar to drawing a 4 dimensional shape in 3 or even 2 dimensions.\n\nEuclidian geometry doesn't allow triangles with a sum of all angles to be greater than 180 degrees.

yes we did it in science class.  I forget how exactly but you fold the paper and then start cutting tiny rows but everyother row you change directions and then open it up when you are done and you get a loop of paper like a hoop and then you can step through it.  E-mail me for more details at fairy_dust_xo@yahoo.com  Hope this helps!

Well, if you think about it, you shouldn't have to copy. To make any shape 3D from 2D, just give it DEPTH. Draw lines slightly up and tilted from each corner, then connect them accordingly. It's super easy once you get the concept.\n\nFor pictures, go to www.mathworld.com and search for cubes, prisms, etc.

Easiest way would be to drop a bisector from two of the angles.  The intersection will be the centroid.  This is assuming a regular pentagon.\n\nIf it is an irregular pentagon, you could tie a weight to a string.  Hold the pentagon by a vertex while also holding the string.  This line passes through the center of gravity.  Do the same for another vertex.  The lines will intersect at the centroid (aka center of gravity).  This method would work for a regular pentagon also since the lines would be the angle bisectors.
