  • Friction

    Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction: Dry friction is a force that opposes the relative lateral motion of two solid surfaces in contact. Dry friction is subdivided into static friction ("stiction") between nonmoving surfaces, and kinetic friction between .

  • Transducer Cone Angle 101: How to Pick the Ideal Cone Angle .

     · The cone angle on fish finder transducers, also known as a beam angle, determines how wide a beam of sound/radio waves are shot out into the water column towards the sea, river, or lake bottom.. A wider, bigger beam angle of sound waves will give you coverage of a larger area to see in an image on your display. For example, a sonar unit using 200 kHz sound .
