31. This variation in the shape of Io causes frictional heating in its interior. 32. The component of the GRF parallel to the surface is the frictional force. 33. Traveling in such a bubble held the potential to reduce the frictional drag radically. 34. Carbon-carbon disc brakes are used for reduced weight and increased frictional performance. 35. The water is created from ice that melts under high pressure from frictional heating. 36. Viscous effects introduce frictional losses and time dependence. 37. The synchro ring rotates slightly due to the frictional torque from the cone clutch. 38. A longer term form of frictional unemployment is structural unemployment which is very similar. 39. Frictional heat is generated between the wear-resistant tool and the work pieces.40. Mortensen's research focused on frictional unemployment.
