Study Notes
Introduction to the Subject Matter
- The book aims to present each topic and problem from fundamental concepts in the simplest way possible, suitable for an average student.
- A large number of solved, unsolved, and graded examples are included, drawn from recent university and professional exam papers. This familiarizes students with common exam question types.
- Practice exercises accompany each topic, with answers provided. However, these answers are not guaranteed error-free.
- Chapter highlights summarise main topics aiding quick revision before exams.
- The author strives for accuracy but acknowledges the possibility of errors and welcomes corrections for future editions.
Units and Measurements
- Fundamental units: The book discusses fundamental units, including the metre and kilogram.
- Derived units: The text elaborates on derived units, such as density (kg/m³), force (N = kg·m/s²), pressure (Pa = N/m²), stress (Pa), work (J = N·m), and power (W = J/s).
- SI units: The International System of Units (SI) is outlined.
- Metre: The international metre is defined as the distance between two parallel lines engraved on a platinum-iridium bar. This standard is maintained by the International Bureau of Weights and Measures.
- Kilogram: The kilogram is another central fundamental unit.
- General Conference on Weights and Measures (GCWM): This international organization sets the definitions of units used in science and technology.
Mathematical Concepts
- Algebra (power zero): Anything raised to the power of zero equals one (a⁰ = 1 ; x⁰ = 1).
- Algebraic multiplication and division (same bases): If the bases are the same, for multiplication ( xm × xn = xm+n) and division (xm/xn = xm-n).
- Derivatives (quotient rule): The text describes calculating differentials of functions based on quotient rule.
- Derivatives (trigonometric functions): The differential coefficients of trigonometric functions such as sinx, cosx, tanx, and cotx are defined.
- Derivatives (important note): The derivative of a function equals zero means the function is either maximum or minimum and this fact can help find maximum or minimum values.
Integral Calculus
- Integration symbol: The integral symbol (∫) is defined.
- Integration of powers of x: To integrate any power of x, add 1 to the exponent and divide by the new exponent.
- Integration of constants: Integrating a constant involves multiplying the constant by the variable. ∫C dx = Cx.
Engineering Applications Covered
- The content covers elastic constants.
- Principal stresses and strains.
- Limit of eccentricity.
- Dams and retaining walls.
- Deflection of beams.
- Deflection of cantilevers.
Abbreviation Usage
- The book uses abbreviations: t, s, min, N, N-m, kN-m, rad, rev, and more.
