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.




Loadn and unloand of heavy artifacts


...refrigerator...

...like...

...and...

...in my bullet...

...-s...

...mmmmn...

...and any in tin can...

...beans...

...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...

..can be a myth...

...did it all via teleport...

...and...!...

...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...!!?...

...what...

...you know...

..do...
