What is the mechanical equivalent of voltage?
Key Concept: Analogous Quantities
| Electrical Quantity | Mechanical Analog I (Force-Current) | Mechanical Analog II (Force Voltage) |
|---|---|---|
| Voltage, e | Velocity, v | Force, f |
| Current, i | Force, f | Velocity, v |
| Resistance, R | Lubricity, 1/B (Inverse friction) | Friction, B |
| Capacitance, C | Mass, M | Compliance, 1/K (Inverse spring constant) |
What is the analogy between mechanical and electrical systems?
Electrical systems and mechanical systems are two physically different systems. There are two types of electrical analogies of translational mechanical systems. Those are force voltage analogy and force current analogy….Torque Current Analogy.
| Rotational Mechanical System | Electrical System |
|---|---|
| Angular velocity(ω) | Voltage(V) |
What is difference between electrical and mechanical impedance?
That is, a mechanical impedance is represented as an electrical impedance and a mechanical resistance is represented as an electrical resistance in the electrical equivalent circuit. Elements that are in series in the mechanical system are in parallel in the electrical equivalent circuit and vice versa.
What is the unit of mechanical impedance?
Ohm (mechanical, SI) is the only unit in the category of Mechanical impedance in our database. It is also known as ohms. This unit is commonly used in the SI unit system. Ohm (mechanical, SI) has a dimension of ML-4T-1 where M is mass, L is length, and T is time.
What are the basic elements in the rotational mechanical systems?
As with translating mechanical systems, there are three fundamental physical elements that comprise rotating mechanical system: inertia elements, springs and friction elements.
What is the mechanical equivalent of a capacitor?
spring compliance
is called the spring compliance.
What do you mean by mechanical impedance?
Mechanical impedance is defined as the ratio of a force-like quantity to a velocity-like quantity when the arguments of the real (or imaginary) parts of the quantities increase linearly with time [69]. From: Medical Engineering & Physics, 2012.
What is electrical resistance formula?
The electrical resistance of a circuit component or device is defined as the ratio of the voltage applied to the electric current which flows through it: If the resistance is constant over a considerable range of voltage, then Ohm’s law, I = V/R, can be used to predict the behavior of the material.
How is an electrical circuit like a mechanical system?
To apply this analogy, every node in the electrical circuit becomes a point in the mechanical system. Ground becomes a fixed location, resistor become friction elements, capacitors become masses and inductors become springs. Sources must also be transformed. A current source becomes a force generator, and a voltage source becomes an input velocity.
How is an electrical circuit converted to a mechanical 1 analog?
The conversion from an electrical circuit to a mechanical 1 analog is easily accomplished if capacitors in the circuit are grounded. If they are not, the process results in a mechanical system where positions must be chosen very carefully, and the process can be much more difficult.
How is Capacitance measured in a mechanical analogy?
Since the energy of the mass in a Mechanical 1 analogy is measured relative to mechanical ” ground ” (i.e., velocity=v=0) the energy of the capacitance must be measured relative to electrical ground (i.e., voltage=e=0). To apply this analogy, every node in the electrical circuit becomes a point in the mechanical system.
What are the analogies between electrical and mechanical systems?
Mechanical–electrical analogies are the representation of mechanical systems as electrical networks. At first, such analogies were used in reverse to help explain electrical phenomena in familiar mechanical terms.
