Several examples of the construction of Bode Plots are included in this file. Click on the transfer function in the table below to jump to that example. Draw the Bode Diagram for the transfer function: Step 1: Rewrite the transfer function in proper form. Make both the lowest order term in the numerator and denominator unity. The numerator is an order 0 polynomial, the denominator is order 1. Bode Plot Examples
Bode plot Figure 1(a): The Bode plot for a first-order (one-pole) highpass filter; the straight-line approximations are labeled "Bode pole"; phase varies from 90° at low frequencies (due to the contribution of the numerator, which is 90° at all frequencies) to 0° at high frequencies (where the phase contribution of the denominator is −90° and cancels the contribution of the numerator). Figure 1(b): The Bode plot for a first-order (one-pole) lowpass filter; the straight-line approximations are labeled "Bode pole"; phase is 90° lower than for Figure 1(a) because the phase contribution of the numerator is 0° at all frequencies. Overview Among his several important contributions to circuit theory and control theory, engineer Hendrik Wade Bode (1905–1982), while working at Bell Labs in the United States in the 1930s, devised a simple but accurate method for graphing gain and phase-shift plots. These bear his name, Bode gain plot and Bode phase plot.
Mechanical Engineering | MIT OpenCourseWare | Free Online Course Materials A student in Professor Martin Culpepper's Course 2.72 Elements of Mechanical Design races to work down a steel rod with the lathe his team made as part of a final challenge. One of the six founding courses of study at MIT, Mechanical Engineering embodies the motto “mens et manus” — mind and hand. Disciplinary depth and breadth, together with hands-on discovery and physical realization, characterize our nationally and internationally recognized leadership in research, education, and innovation. MIT mechanical engineers have always stood at the forefront in tackling the engineering challenges of the day: inventing new technologies, spawning new fields of study, and educating generations of leaders in industry, government, and academia.

Dynamic Systems - Block Diagram Problems
Overview The difference between these two approaches is not the goal itself, but rather the prime approach to achieving it. The implementation of smooth flow exposes quality problems that already existed, and thus waste reduction naturally happens as a consequence. Lean manufacturing
Gases - Ratios of Specific Heat Heat capacity of a gas in a constant pressure process - to heat capacity in a constant volume process Internal Energy For an ideal gas the internal energy - u - is a function of temperature and the change in internal energy can be expressed as du = cv dT (1) where du = change in internal energy cv = specific heat for the gas in a constant volume process dT = change in temperature
Pressure Conversion - Convert Pascal, Kpa, Mpa, Bar, Torr, Psi, Atm Pressure conversion calculator for several SI (metric) and other commonly used pressure units. Pressure unit in SI system is pascal (derived SI unit not base unit). It is equivalent to one newton per square meter. Other common units are kilopascal (kpa), megapascal (mpa), psi (pound per square inch), torr (mmHg), atm (atmospheric pressure) and bar. Pressure is the amount of force applied per unit area. The calculation formula is: Pressure = Force / Area
The Individual and Universal Gas Constant The Individual and Universal Gas Constant in fluid mechanics and thermodynamics The Individual and the Universal Gas Constant are known from the Ideal Gas Law. The Individual Gas Constant - R The Individual Gas Constant depends on the particular gas and is related to the molecular weight of the gas. The value is independent of temperature.
