# Mechanical Engineering Calculations

**Cantilever Beam**- A beam that is held in an encastre at one end whilst the other end is unsupported.
**Cutting Speed**- The surface speed of the workpiece in a lathe or a rotating cutter.
**Froude Number**- A dimensionless number used in the study of fluid flow problems with models.
**Leaf Springs**- Either a simple beam used as a spring or laminations of steel.
**Moments of Inertia**- Principal axes for bodies of uniform density.
**mpg**- Abbreviation of mile per gallon.
**Prandtl Number**- A dimensionless group often used in heat exchange calculations.
**Quarter Wave Tube**- A resonator used most commonly on automotive air intake systems to reduce resonance.
**Reynolds Number**- This is a non-dimensional number (consistent units) which describes whether fluid flow is laminar, turbulent, or transitional between the two.
**Springs**- The physics of simple springs - helical and beam forms.
**Thin Rod**- The moment of inertia of a thin rod.
**Torque**- The torque or turning moment acting on a body is defined as the product of the magnitude of the force and the perpendicular distance of the line of action of the force from the axis about which the body is being rotated.
**Wheel**- The Mesopotamians are credited with the invention of the wheel.
