| Sep 24, 2013 at 17:12 | comment | added | DA01 | @ChrisCudmore this would probably be a good, separate question, but: I've always learned that lag bolts provide more strength (in terms of resisting pull-out) than through-bolts (the theory being more thread is in contact with the wood in a lag bolt than there is thread in contact with the nut in a through-bolt) | |
| Sep 24, 2013 at 17:06 | comment | added | Chris Cudmore | This can be dealt with, you just need to be aware of it. | |
| Sep 24, 2013 at 17:00 | comment | added | HerrBag | @ChrisCudmore Agreed, pulley tension is 2T, eyelet (endpoints) tension is 1T | |
| Sep 24, 2013 at 16:37 | comment | added | Chris Cudmore | Tension in the rope is assumed to be constant throughout. Look at your lower right pulley. There is a force of 2 T pulling it to the left. Therefore, there needs to be a force of 2 T pulling it to the right. Otherwise, F = MA -> A = F/M will result in rapid acceleration to the left. | |
| Sep 24, 2013 at 16:23 | comment | added | HerrBag | @chriscudmore I think the force is 1x only, because the pulleys are fixed and can't adjust the length. Pulley blocks trade off lower (or higher) force by requiring more rope motion. | |
