| Jul 22, 2015 at 18:04 | comment | added | most venerable sir | @mbeckish, is it ever possible that tension be directed toward the mass? | |
| Jul 22, 2015 at 18:02 | comment | added | mbeckish | Try it yourself - tie a string to a block, and grab the other end of the string with your hand. Now, try to use the string to move the block away from your hand. You can't, because the string goes limp. Now try to use the string to move the block towards your hand. | |
| Jul 22, 2015 at 18:00 | comment | added | mbeckish | Because the string "pulls" upward - if the force were pointing down, the string would be "pushing" the block. | |
| Jul 22, 2015 at 17:55 | comment | added | most venerable sir | @mbeckish, then why isn't the tension for the string attached to the hanging mass going down? | |

| Jul 22, 2015 at 13:54 | comment | added | mbeckish | Here's an easy way to get it right, without worrying about "why": a string can only pull. If you try to push with a string, it will just fold up. | |
