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.
