Problem 5-24

The relay regulates voltage and current. Determine the force in the spring CD, which has a stiffness of k = 120 N>m, so that it will allow the armature to make contact at A in figure (a) with a vertical force of 0.4 N. Also, determine the force in the spring when the coil is energized and attracts the armature to E, figure (b), thereby breaking contact at A. 50 mm50 mm 30 mm (a) (b) D D k k C B C EA B A 10 Prob. 524

What is tribology Fundamentals of Tribology: • Surfaces in Contact • Friction • Lubrication • Wear •Two aspects – Science: Basic mechanisms – Technology: Design, manufacture, maintenance What is Tribology • Tribology is defined as the science of interacting surfaces in relative motion. • The word tribology comes from the Greek tribos, meaning rubbing. • In any machine there are lots of component parts that operate by rubbing together. • Some examples are bearings, gears, cams and tappets, tires, brakes, and piston rings. All of these components have two surfaces which come into contact, support a load, and move with respect to each other. • Sometimes it is desirable to have low friction, to save energy, or high friction, as in the case of brakes. Usually we don't wan
