Gross weight load

Dear native English speaking professionals!
Would someone please advise on the term "gross weight load" - is it possible to use it for gravity force of a fully loaded railcar?

I use it in the following context:

"Estimated vertical force on one chord section is assumed to be equal to:
q(v) = P(gr) : n
where P(gr) is gross weight load;
n is number of car dumper clamps; it is assumed that n = 8 (4 per side)."

Is it OK to use this term here? Being no native English speaker, I'm not 100% sure...

Hi Altai! :smile:

I'm not familiar with transport terminology :redface:, but I've always understood gross weight to include the load, and net weight to exclude the load …

see http://en.wikipedia.org/wiki/Gross_weight#Measuring_weight"
Gross weight is a term that generally is found in commerce or trade applications, and refers to the total weight of a product and its packaging. Conversely, net weight refers to the weight of the product alone, discounting the weight of its container or packaging; and tare weight is the weight of the packaging alone.​

So the word "load" would be unnecessary (I think).

Thanks for your reply tiny-tim.
I was also thinking about "gross weight force", but... again, I'm not so sure. Though what "P" stands for is really a force due to the weight of a fully loaded railcar - including the weight of the car itself (tare weight) and the weight of its contents (net weight).

Hi Altai! :smile:

Weight is a force.

m is mass, and mg is weight.

Of course, a lot of people say "weight" when they mean "mass" …

who is this being written for?​

It's for English-speaking railwaymen. I'm just translating some Russian material into English.
So the "force" part is also excessive here? Oops.

mmm … I don't really understand why a railwayman would be interested in force :confused:

what calculations do they need to make?

Don't they simply want to know what the weight (the mass) is?

Well, the material is about all kinds of loads and forces acting on a railcar, so why not?

Tare weight = weight of the empty container or car
Net weight = weight of the contents of the container or car
Gross weight = total of Tare and Net weights

These figures are displayed on the sides of shipping containers, for instance
