Maximum tension on a string

Tags:
  1. Nov 30, 2014 #1
    if one string can hold a block of 100kg, how much weight can two strings connecting the ceiling and one single point hold a block?? is it 200 kg? if yes, then what about one string connecting the ceiling and one single point of the block two times, three times or more? [im sorry if the grammar is wrong] will the weight that string can hold the block increase as well? e.g. 1000 kg if ten times??

    Why do you emphasize that the strings connect to the block in a single point? Is 100kg what the string can hold, or what that attachment can hold?

    because there is a hole on the block, the string goes through the hold to connect the ceiling and the block.

    You have to specify where the 100kg limit comes from, the string or the attachment. If it's the string's limit and the attachment can hold any weight, then adding more strings will allow you to hang more weight.

    Yes, if the sharp bend at the hole doesn't somehow weaken or cut the string, or if the strings somehow align poorly and the friction doesn't allow the load to be evenly distributed among the strings. But basically yes, if you loop the string around the object and reattach it to the ceiling, it can hold twice as much as just tying it to the ceiling and to the object.

    how can about looping 10000 times? if that is the case, then the string can hold 1 million kg?

    Yes, I would think so, but you might need to worry about whether or not the load is evenly distributed, with a lot of strings it would become problematic.
