Calculate maximum weight box can hold

AI Thread Summary
To determine the maximum weight a box can hold, the tensile strength of the tape is important, but the quality of the adhesive bond is crucial as well. The force exerted on the tape equals the weight of the contents inside the box. A practical method to assess the tape's strength is to tape the box shut and gradually add weights until the tape fails. This experiment will help gauge both the tape's tensile strength and the effectiveness of the glue. Understanding these factors will provide a clearer indication of the box's weight capacity.

hi,
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
 
Engineering news on Phys.org
the force on the tape is the weight of the object in the box

tensile stress = force / areaHowever, 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
 

Thread 'Query on Isentropic relationships (such as PV^gamma = constant)'

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...

Thread 'Dry sump pump issue'

I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
