Some of the terms used in mechanics are defined below. Force Our earliest ideas concerning forces arose because of our desire to push, lift, or pull various objects. So force is the action of one body on another. Our intuitive concept of force includes such ideas as place of application , direction, and magnitude, and these are called the characteristics of a force.

For example, if the force operating on a journal bearing becomes too high, it will squeeze out the oil film and cause metal-to-metal contact, overheating, and rapid failure of the bearing.

Efficiency
Mechanical Efficiency is the ratio of work input to work output. It is often expressed as a percentage. The efficiency of an ideal machine is 100 % but an actual machine's efficiency will always be less than 100% because of the Second law of thermodynamics which states that the quality of energy will decay, eventually becoming heat. This means that some of the work put into the system is transformed (lost) into thermal energy (heat). In a mechanical system, friction is the most common cause of the work lost to heat.

Lesson 31 Mechanism of Surface Finish Production
Under some conditions, this vibration will reach and maintain a steady amplitude whilst under other conditions, the vibration will built up and unless cutting is stopped, considerable damage to both the cutting tool and workpiece may occur.This phenomenon is known as chatter and in axial turning is characterised by long pitch helical bands on the workpice surface and short pitch undulations on the transient machined surface.

Background
•
The first schools in the United States to offer an engineering education were the United States Military Academy in 1817, an institution now known as Norwich University in 1819, and Rensselaer Polytechnic Institute in 1825. Education in mechanical engineering has historically been based on a strong foundation in mathematics and science; this is followed by courses emphasizing the application of this knowledge and studies in the social sciences and humanities to give the engineer a broader education.

Lesson 19 Screws, fasteners and joints 一、Background information
Theory The clamp load, also called preload, of a cap screw is
created when a torque is applied, and is generally a percentage of the cap screw's proof strength. Cap screws are manufactured to various standards that define, among other things, their strength and clamp load. Torque charts are available that identify the required torque for cap screws based on their property class or grade.
