Do electric cars have internal combustion engines? All-electric vehicles (EVs), also referred to as battery electric vehicles, have an electric motor instead of an internal combustion engine. Because it runs on electricity, the vehicle emits no exhaust from a tailpipe and does not contain the typical liquid fuel components, such as a fuel pump, fuel […]

What is vision and mission statement and with example? Difference Between Vision and Mission Statements: 25 Examples. Definition of vision and mission: A vision statement focuses on tomorrow and what an organization wants to ultimately become. A mission statement focuses on today and what an organization does to achieve it. Both are vital in directing […]
What methods transform analog IIR filter to digital IIR filter?
What methods transform analog IIR filter to digital IIR filter? As a result, usually, when a digital IIR filter is going to be implemented, an analog filter (e.g. Chebyshev , Butterworth, Elliptic, etc) is first designed and then is converted to a digital filter by applying discretization techniques such as: 1)Bilinear transform or 2) Impulse […]
How many classifications of Mewps are there?
How many classifications of Mewps are there? MEWP Terminology and Classification MEWPs will now be classified into “groups” and sub-divided into three “types.” Are scissor lifts considered scaffolding? Scissor lifts are mobile supported scaffold work platforms used to safely move workers vertically and to different locations in a variety of industries including construction, retail, entertainment […]
Are single crystals isotropic or anisotropic?
Are single crystals isotropic or anisotropic? Most single crystals show anisotropy in certain properties, such as optical and mechanical properties. An amorphous substance, such as window glass, tends to be isotropic . This difference may make it possible to distinguish between a glass and a crystal. What is the difference between single crystal and polycrystalline? […]
Can you make a precipitation hardened 2014 aluminum?
Can you make a precipitation hardened 2014 aluminum? A solution heat-treated 2014 aluminum alloy is to be precipitation hardened to have a minimum yield strength of 345 MPa (50,000 psi) and a ductility of at least 12%EL. Specify a practical precipitation heat treatment in terms of temperature and time that would give these mechanical characteristics. […]
Are voltage dividers efficient?
Are voltage dividers efficient? Dividers as regulators offer very poor efficiency, very poor line regulation and very poor load regulation. A voltage divider is a very good way to get a lower voltage reference point but it cannot be used to deliver any power. When should you use a voltage regulator? Voltage regulators are designed […]
How efficient is a turbine engine?
How efficient is a turbine engine? With increasing temperature, intake air becomes less dense and therefore the gas turbine experiences power loss proportional to the increase in ambient air temperature. Latest generation gas turbine engines have achieved an efficiency of 46% in simple cycle and 61% when used in combined cycle. Which type of engine […]
