They are big rolls of plastic sheets. They are usually sitting there but I wanted to know the breaking strength of the straps (in lbs) needed in order to prevent them from separating as they will eventually be shipped via trucks.russ_watters said:
What would cause any side-to-side motion that would stress the strap? How are the rolls packaged for lifting into the trucks? Why do you need to join pairs of them instead of crating several all together? How are they unloaded at the destination? Have you discussed this with the trucking company to get their ideas?anima said:
Understood. Without external forces, anything would hold them together. Now, what if the question was changed where there is a third wheel stacked on top of the other two. What forces would be acting on each wheel on the bottom.berkeman said:
You forgot to draw the little stick figure person below that roll with a very scared look on their face...Lnewqban said:
I was thinking something similar, but I don't know shipping: is there an impact scenario where they have to remain attached? What if they are shipped by air, and the g-forces from the plane have to be included?Lnewqban said:
The material and the wrapping are very important.anima said:
The required strength of a strap connecting two rolls depends on various factors such as the weight of the rolls, the distance between them, and the force applied on the strap. It is important to calculate the load-bearing capacity of the strap to ensure it can withstand the weight and force without breaking.
The required strength of a strap can be calculated by first determining the weight of the rolls and the distance between them. Then, the force applied on the strap needs to be calculated. Finally, the load-bearing capacity of the strap needs to be compared to the calculated force to determine if it is strong enough.
If a strap with insufficient strength is used to connect two rolls, it can lead to the strap breaking, causing the rolls to fall and potentially causing damage to the rolls or surrounding equipment. It can also pose a safety hazard to anyone in the vicinity.
Yes, there are industry standards for the required strength of a strap connecting two rolls. These standards vary depending on the type of rolls and the industry they are used in. It is important to consult these standards and ensure the strap meets the necessary requirements.
Yes, the required strength of a strap can change over time. Factors such as wear and tear, environmental conditions, and changes in weight or force applied can affect the strength of the strap. It is important to regularly inspect and replace straps as needed to maintain the required strength.
