WebApr 13, 2024 · 3.1.1 Law of Friction. When two objects are in contact, there must be a tangential force in order to produce a relative displacement between them. When the tangential force is increased from zero to a finite value, a micro-displacement is produced in the contact area, but the two objects contacted at this time remain motionless as a whole … WebJun 28, 2024 · To summarize, conductor spacing on a circuit board is measured in two ways—creepage and clearance: Creepage: This is the distance between two conductors on the surface of the board or along the surface of the insulating material. Clearance: This is the line-of-sight distance between two conductors through the air. is michael on 911 leaving the show
