Engine Cycle

Strain (ε) – A dimensional change per unit length of a stressed member.
Do the counterweights on a propeller tend to move the blades toward high or low pitch? – High pitch
external effect of Force – changes or tend to change the state of motion of body
-engineering mechanics
Surrounding – the region outside the boundary or space
HOW IS WORK EVALUATED AND MEASURED? – power
Career – Profession where one trains and is undertaken as a perm calling
soil mechanics – define the behavior of soil
True Strain – True strain = ln(l/lo). Unlike engineering strains, true strains are consistent with actual physical phenomena in the deformation of materials.
Ideal Mechanical Advantage – A ratio of distance traveled by the applied effort and resistance force within a system
What does CoF stand for and what does it mean? – Co-efficient of Friction

The ratio of friction between two bodies, and the force pressing them together

Gear Hobbing – A special form of manufacturing that cuts gear tooth geometries. It is the major industrial process for cutting involute form spur gears of.
static equilibrium – a condition where there are no net external forces acting upon a particle or rigid body and the body remains at rest or continues at a constant velocity.
In GD&T, ___ of a surface specifies a 3D tolerance zone defined by two contoured surfaces. When a datum reference is not specified, the tolerance controls only the shape of the contour. When datums are specified, the tolerance controls the shape of the contour as well as the size and/or location of the contour. – profile
The norms and values that people actually follow – Real Culture
Acceleration – Sự tăng tốc

chain whell (n)
(a toothed pulley or sprocket used for transmissing torque by a chain) – koło łańcuchowe
what are the types of movement? give example – -most systems are composed of a variety of moving pieces. They are based on two types of movements that are associated with specific symbols: translation, rotation
types of movements:
-pulley (rotation)
-bicycle pump (translation)
-sliding window (translation)
-corkscrew (rotation)
-dreidel (rotation)
