Calculate maximum weight box can hold

  1. Jul 25, 2015 #1
    This is probably very simple issue, but i am not an engineer nor have an understanding of basic physic..... I need to calculate if the tape used to connect (sealed) to ends of the cardboard box will withstand the weight of the product i put inside it. I have a tape properties (tensile strength etc.). i just don't know how to calculate maximum weight i can put inside.
    Can anyone help please?
    Thank you very much

    the force on the tape is the weight of the object in the box

    tensile stress = force / area

    However, the tensile strength of the tape is not the determining factor!

    How good is the glue. A very strong tape weakly bonded will fail.

    Thank you William. So if I could measure somehow how strong is the tape when glued on the cardboard that should give me an indication on how strong is the glue right?

    yes, if this is an experiment you could do that.

    Tape the box shut, and incrementally add weights until the tape failed. That will give you a sense of the strength of the bond
