    Study Notes

    Capital Recovery and Annuities

    • The capital recovery factor (A/P, i, n) relates to uniform series sinking fund factor (A/F, i, n) through various formulas, though specific relation not confirmed.
    • An annuity is defined as a series of uniform amounts received over time, contrasting with a lump sum payment.

    Financial Comparisons and Calculations

    • Net present worth analysis can be invalidated by non-conventional cash flows, different evaluation periods, different project magnitudes, and mutually exclusive projects.
    • Future worth (F) of a present amount (P) can be calculated as F = P(1+i)ⁿ, where i is the annual rate of return and n is the number of years.

    Investment Characteristics

    • Two investments with the same present worth but different lives will possess different equivalent uniform annual cash flows, differing salvage values, or potentially identical salvage values.

    Material Properties and Metallography

    • Gray cast iron contains iron carbide, while ductile iron features graphite in the form of flakes or spheroids.
    • Metallographic preparation of iron specimens enhances grain boundary visibility through polishing, mounting, and etching techniques.

    Alloy Characteristics

    • Small molybdenum additions to low alloy steels enhance heat treatment effectiveness.
    • Low alloy steels are primarily characterized by small nickel and chromium content.
    • Nonmagnetic stainless steels predominantly contain high nickel levels and are classified into martensitic, austenitic, and ferritic types.

    Corrosion Resistance

    • A minimum chromium content of 11% is essential for stainless steel to be considered corrosion resistant.

    Electrostatics and Magnetic Fields

    • Coulomb's force (F) between two charges diminishes with the square of the distance (1/r²).
    • Magnetic field lines exhibit consistent properties: they do not cross, have no ends, and indicate greater strength where lines are closely spaced.

    Electrical Quantity Definitions

    • Tesla is the unit of magnetic flux density.
    • Magnetic flux lines do not exhibit sources or sinks; they form continuous loops.

    Behavior of Conductors in Magnetic Fields

    • No current flows in an open-circuited conductor despite its motion through a magnetic field, and lines of flux indicate directionality.

    Generators and Power Systems

    • Modern locomotives utilize DC motors powered by DC generators, driven by diesel engines for efficiency and operational stability.

    Parallel Shunt Generators

    • Parallel operation of shunt generators offers stable load characteristics, ease of maintenance, and flexibility in system configuration.
