minus-square@[email protected]linkfedilinkEnglish18•8 months agoWelcome to engineering, where we have MPa as a unit of stress and mm/mm as a unit of strain!
minus-square@[email protected]linkfedilinkEnglish2•8 months agoWhy km/h (or mph) and not ft/year? Because the numbers have a nicer magnitude then.
minus-square@[email protected]linkfedilinkEnglish7•8 months agoDoesn’t apply here, say for example i have a piece of steel with length 100mm and it stretches 10mm, is mm/mm the strain would be 0.1 mm/mm, in meters it would be 0.1m/m Really strain is dimensionless but occasionally people add units
minus-square@[email protected]linkfedilinkEnglish3•8 months agoI feel like I should’ve spotted that… they’re the same units. 🤦
minus-square@iAvicennalinkEnglish2•8 months agoI was told that you also sometimes have four basis vectors in 3D
That’s pressure.
Pushing down on me.
Pressing down on you.
no man ask for.
Under pressure that burns a building down
Splits a family in two
puts people on streets
Welcome to engineering, where we have MPa as a unit of stress and mm/mm as a unit of strain!
mm/mm?? why not call it m/m?
Because we’re precise!
