Did you know?

Stiction has been a part of the English language since at least 1946, when it appeared in a journal of aeronautics. While stiction refers to the force needed to get an object to move from a position at rest, it is not related to the verb stick. The word is a blend word formed from the st- of static (“of or relating to bodies at rest”) and the –iction of friction (“the force that resists relative motion between two bodies in contact”). So, basically, it means “static friction” (or to put it another way, “stationary friction”).


Stiction is stationary friction. Starting the bolt turning takes more force than keeping it turning. The tighter the bolt, the more stiction can affect torque readings.” — Jim Kerr, SRTForums.com, 4 Mar. 2004

“The theme of blue continues on the fork stanchions. The upside-down fork itself is the same Showa unit seen on the standard bike, but in this case the inner tubes feature a special nitride coating to help reduce stiction and provide a smoother stroke.” — Zaran Mody, ZigWheels.com, 14 Apr. 2020
