Exercise: Supplies Logistics : Force of Abrasion and Friction
Situation
You can measure the force of friction and abrasion by using specialized testers or simple force gauges to record the resistance and material loss when two surfaces rub together. [1, 2]

...oh... ...
How to Measure Friction Force
Sled Test Method: Place a weighted metal block (sled) on top of a flat test surface. Connect the sled to a force gauge or spring scale and pull it horizontally.
Static Friction: Record the peak force required to make the stationary sled start moving.
Kinetic Friction: Record the average force needed to keep the sled sliding at a steady speed.
Coefficient of Friction (COF): Divide the measured friction force (in Newtons) by the normal force (the weight of the sled). [1, 2, 3, 4]
How to Measure Abrasion Force and Resistance
Abrasion Test Rig / Usometer: Clamp a material sample into an arm that rubs it against a cylinder, abrasive paper, or calibrated grinding wheels at a set angle or pressure. [1, 2]
Frictional Pull Force: Record the continuous force required to scrape or rub the material. A force-versus-distance graph will show peaks indicating stick-slip behavior and mean friction force. [1]
Mass Loss or Wear: Weigh the sample before and after the test to find the exact mass lost, or inspect surface scratches using an optical microscope or optical density measurement. [1, 2]

Abrasion Test Rig
In a typical abrasion test using the Abrasion Test Rig, a sample of the abrasive material is held in place in a self-tightening grip. As the test is carried out, the arm of the Texture Analyser draws the sample under and around a cylinder at 90 degrees and the force required to pull the material is recorded.

...and [ baked beans ]...
...or anything...
...supplies...
...yeah...
...near to the loading bay...
..and the vehicle...
...owhhh...!?...
...can we lay a [ flooring ]...
...that will slide them over...
..and easier..
...then...
...laying out a new...
...and mini depot...
...will be easy...
...easier...
...ohhh...!...
...
...can [ the ] kit...
...clothing....
- boots/vests...
...on that we keep...
...our own...
...owhhh...!...
...more in...
- [ gun[s]/patrol equipment ]...
...i dare say...
...and...
.- building materials...
...the flooring...
...in the [ depot ] cabins...
...and all...
...owhhh...
...then do...
...give me a chute...
...so i drag..
...will...
...then hope no in dead...
...and concealed by that...

...in their jing...
...they lie...
...about who....
...and in where...
...owhhh...!...!...
...
...don't slip...!..
...no won't...
-> NEED to review optimal low friction surfaces for these types of supply loading and unloading tasks...
..yeah do...
...and...
...i...
...do...
...yes...
...mmmm...
...owhhh...!... ...!...
...then do...
...oh find a machine...!!?...

ADDENDUM
Military supplies are organized into 10 official classes of supply to manage logistics and planning. [1]

The 10 Classes of Supply
Class I – Subsistence: Food, drinking water, and gratuitous health and comfort items.
Class II – Clothing and Equipment: Individual gear, tents, tools, maps, and administrative supplies.
Class III – POL (Petroleum, Oil, and Lubricants): Fuels, hydraulic fluids, coolants, and antifreeze.
Class IV – Construction Materials: Fortification, barrier, and engineering installation materials.
Class V – Ammunition: Bullets, explosives, mines, grenades, rockets, and pyrotechnics.
Class VI – Personal Demand Items: Non-military sales items like hygiene products, snacks, and tobacco.
Class VII – Major End Items: Large complete systems such as tanks, vehicles, and launchers.
...might tow that... ...with a winch... ...and across clear/smooth ground... ...mmm...
...yeah...
Class VIII – Medical Materiel: Medicines, surgical supplies, and blood products.
Class IX – Repair Parts: Component kits and assemblies for equipment maintenance.
Class X – Non-military Programs: Material supporting non-military projects like economic or agricultural development. [1, 2, 3, 4, 5]
-> NEED to review forecast volumes per month of :
general military supplies (clothing/camping gear)
tactical equipment
intended use case and activity
...
...yes...
...and de un you...!...
...ehhh...
...heyyy...!...
...
