Some Mathematical Notation and Mechanical
quantities

• The symbol to denote the equality of two
  quantities
• (Example x4, x is equal to 4)
• The symbol a is used to denote the
  proportionality
• (Example a a b2 means that a is
  proportional to the square of b)
• The symbol lt means less than, and gt means
  greater than
• (Example agtb means a is greater than b)
• The symbol ltlt means much less than, and gtgt
  means much greater than
• The symbol is used to indicate that
  two quantities are approximately equal to each
  other

4

• The symbol means is defined as
• ?x (delta x) means the change in the quantity x.
• a x b means the product of a and b
• (Example 2x816, the product of 2 and 8 is
  equal to 16)
• plus, - minus, x
  multiply,
  divide
• (Example 4 divided by 2 is equal to 2)
• 3x10-4 three times ten to the minus four
• ? (Capital Sigma) to sum several
  quantities
• x the magnitude of a quantity x, or absolute
  value of x

5

• POWERS OF TENVERY LARGE NUMBERS (Astronomy,
  High Energy Particle Accelerators) or VERY SMALL
  NUMBERS (cells, molecules, atoms, nuclei, quarks)
  it is most convenient to use "Powers of Ten"
  notation.
• VERY LARGE NUMBERS
• 103 kilo (k) ? ten to the three
  (thousand)
• 106 mega(M) ? ten to the six (million)
• 109 giga(G) ? ten to the nine (billion)
• 1012 tetra(T) ? ten to the twelve
  (trillion)
• VERY SMALL NUMBERS
• 10-3 milli (m) ? ten to the minus three
  (thousandth)
• 10-6 micro(µ) ? ten to the minus six
  (millionth)
• 10-9 nano(n) ? ten to the minus nine
  (billionth)
• 10-12 pico(p) ? ten to the minus twelve
  (trillionth)

6
Some Shapes

• One-two-three dimensional shapes
• a straight line,
  a diagonal line
• a curved line,
  Paralel Lines

a hemisphere
a sphere
Right- triangle or inclined plane
7

• Mechanical quantities can be expressed in terms
  of three fundamental quantities (in the SI
  system)
• mass ? kilograms (kg)
• length ? meter (m)
• time ? seconds (s)
• The denisty of a substance is defined as its
  mass per unit volume
• Units of measurement and their abbreviations
• kilometre (km), metre (m), decimetre (dm),
  centimetre (cm)
• millimetre (mm), square metre (m2), cubic metre
  (m3),
• micrometer (µmmicron)
• i.e. The area of a circle pr2 , The
  circumference of a circle 2pr

Standards and units

• Base units are set for length, time, and mass.
• Unit prefixes size the unit to fit the situation.

• Ax and Ay vector components of A.
• Ax is the magnitude of the x-component
• Ay is the magnitude of the y-component

Vectors

Vector addition

Components of vectors

• Vector components provide a numeric method of
  representation.
• Any vector is built from an x component and a y
  component.
• Any vector may be decomposed into its x
  component using Vcos ? and its y component using
  Vsin ? (where ? is the angle the vector V sweeps
  out from 0).

Calculations using components
17
Unit vectors

• Assume vectors of magnitude 1 with no units exist
  in each of the three standard dimensions.
• The x direction is termed i, the y direction is
  termed j, and the z direction, k.
• A vector is subsequently described by a scalar
  times each component. A Axi Ayj Azk

18
The scalar product

• Termed the dot product.
• Figures illustrate the scalar product.
