What is the difference between plane stress and principal stress? These planes are called the principal planes. It will also be noted from the figure that the normal stresses acting on the planes of zero shear stress are either a maximum or minimum. These normal stresses are called principal stresses. The principal stresses are labelled […]
How do you find the zero input response?
How do you find the zero input response? To find the zero input solution, take the Laplace Transform of the input with f(t)=0 and solve for Xzi(s). Note: since the initial condition was doubled, the zero input response was doubled. How do you find the steady state response from a transfer function? Because when we […]
What is the importance of damkohler number?
What is the importance of damkohler number? A Damköhler number (Da) is a useful ratio for determining whether diffusion rates or reaction rates are more ‘important’ for defining a steady-state chemical distribution over the length and time scales of interest. How is damkohler number calculated? The Damköhler number is defined to be the characteristic mixing […]
Does quality have any meaning in the superheated vapor region?
Does quality have any meaning in the superheated vapor region? Fraction of vapor in liquid-vapor region is called quality. since in superheated zone all the liquid has been vaporised hence it doesn’t have any meaning in superheated region. Does superheated vapor have quality? In thermodynamics, vapor quality is the mass fraction in a saturated mixture […]
What happens to inductor at steady state?
What happens to inductor at steady state? With a steady state DC current flowing through the inductor and therefore zero induced voltage across it, the inductor acts as a short circuit equal to a piece of wire, or at the very least a very low value resistance. What is the impedance of an ideal capacitor […]
What is a transformer symbol?
What is a transformer symbol? When a transformer has a centre tap, the symbol consists of two circles with a line joining one of the circles. Here is alternative qualified version, which also has dots to indicate the instantaneous voltage polarity. At what type of diagram does electrical symbols are applicable? An electronic symbol is […]
How is voltage related with a current B resistance?
How is voltage related with a current B resistance? The relationship between current, voltage and resistance is expressed by Ohm’s Law. This states that the current flowing in a circuit is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit, provided the temperature remains constant. Is voltage A Electric […]
How do you calculate maximum power dissipation?
How do you calculate maximum power dissipation? Therefore, the condition for maximum power dissipation across the load is RL=RTh. That means, if the value of load resistance is equal to the value of source resistance i.e., Thevenin’s resistance, then the power dissipated across the load will be of maximum value. How much power is dissipated […]
What model of communication is a two-way process?
What model of communication is a two-way process? The interaction model of communication describes communication as a two-way process in which participants alternate positions as sender and receiver and generate meaning by sending and receiving feedback within physical and psychological contexts. What are the 4 types of communication models? Let us now learn about the […]
