What to Know About an Object’s Fragility

What to Know About an Object's Fragility

Today, we will look over the design fundamentals of protective cases known as fragility.

Protective cases are usually used when you need to get a delicate item from one place to another. You want to make sure the item doesn’t just get there; it also needs to get there without sustaining damage. To some people, they see protective cases as a simple container that has a little foam lining along the inside. There is much more to a protective case than that. A lot of thought goes into the design of each case. Today, we will look over the design fundamental of protective cases known as fragility.

Fragility

Before you choose how you’re going to protect your equipment, you first have to know the fragility of the equipment. With regards to packaging, fragility is the maximum amount of shock a piece of equipment can handle without taking any damage. For aerospace and defense circles, fragility tends to be expressed in terms of acceleration caused by gravity. This term is known as g-force.  The less shock an object can handle before getting damaged, the more fragile that object is.

Any free-falling object is continuously accelerating. In other words, it continuously gains speed until it reaches the ground, all the way up to the moment of impact. Every free-falling object falls at the same rate as a result of the planet’s gravitational pull. In a vacuum where an object falls vertically without any extraneous factors involved, that object travels at a speed of 9.81 m/s2, also known as 1 g.

Keeping the above information in mind, if an object has a fragility of 10 g, that means it can handle a rate of acceleration that goes up to 10 times Earth’s gravity before taking damage.

How Fragile is My Equipment?

If you bought an item, the original equipment manufacturer (OEM) will likely be able to give you a good idea of the fragility of that item. If you are the OEM, there’s a good chance that a person in the engineering department can give you the information you need on the item’s fragility.

After you have figured out the fragility of your item(s), you will want to know how the equipment is going to be transported. Depending on how your item is transported, it can influence how much shock it sustains for the duration of the trip.
