Contact mechanics print that page

Kontakt_Spannungsoptik

Contact mechanics is foundational to the field of mechanical engineering ; it provides necessary information for the safe and energy efficient design of technical systems and for the study of tribology and indentation hardness . Principles of contacts mechanics can be applied in areas such

Frictional contact mechanics print that page

Frictional contact mechanics is concerned with a large range of different scales. At the macroscopic scale, it is applied for the investigation of the motion of contacting bodies (see Contact dynamics ). For instance the bouncing of a rubber ball on a surface depends on the frictional

electrification. A company called Pacific Amusements in Los Angeles, California , USA produced a game called Contact in 1933. Contact had an electrically powered solenoid to propel the ball out of a bonus hole in the middle of the playfield. Another solenoid rang a bell to reward the player

light emitting diodes (LEDs). A heat sink is physically designed to increase the surface area in contact with the cooling fluid surrounding it, such as the air. Approach air velocity, choice of material, fin (or other protrusion) design and surface treatment are some of the design factors

Non-contact force print that page

A non contact force is a force applied to an object by another body that is not in direct contact with it. The most common example of a non contact force is gravity . A non contact force is different from a contact force , which is a force applied to a body by another body that is

Continuum mechanics print that page

information about the particular material studied is added through a constitutive relation . Continuum mechanics deals with physical properties of solids and fluids which are independent of any particular coordinate system in which they are observed. These physical properties are then represented

Stress (mechanics) print that page

In continuum mechanics , stress is a measure of the internal forces acting within a deformable body . Quantitatively, it is a measure of the average force per unit area of a surface within the body on which internal forces act. These internal forces are a reaction to external forces applied

Bionic contact lens print that page

Bionic_contacts

The bionic contact lens are being developed to provide a virtual display that could have a variety of uses from assisting the visually impaired to the video game industry. [ 1 ] The device will have the form of a conventional contact lens with added bionics technology. [ 2 ] The lens
