2. Grease (lubricant) - Wikipedia

   en.wikipedia.org/wiki/Grease_(lubricant)

   Lithium-based grease has a dropping point at 190 to 220 °C (374 to 428 °F). However the maximum usable temperature for lithium-based grease is 120 °C. The amount of grease in a sample can be determined in a laboratory by extraction with a solvent followed by e.g. gravimetric determination.

3. Lithium 12-hydroxystearate - Wikipedia

   en.wikipedia.org/wiki/Lithium_12-hydroxystearate

   Lithium 12-hydroxystearate exhibits high oxidation stability and a dropping point up to around 200 °C. Most greases used today in motor vehicles, aircraft, and heavy machinery contain lithium stearates, mainly lithium 12-hydroxystearate. [1] Greases can be made with the addition of several different metallic soaps.

   This statement: "Grease-lubricated bearings have greater frictional characteristics at the beginning of operation, causing a temperature rise which tends to melt the grease and give the effect of an oil-lubricated bearing" seems to contradict this one: "Lithium based grease has a drip temperature at 350° to 400°F".

7. Prestressed concrete - Wikipedia

   en.wikipedia.org/wiki/Prestressed_concrete

   Pre-tensioned concrete is a variant of prestressed concrete where the tendons are tensioned prior to the concrete being cast. [1]: 25 The concrete bonds to the tendons as it cures, following which the end-anchoring of the tendons is released, and the tendon tension forces are transferred to the concrete as compression by static friction.
