What is the difference between E400 and E450? The 2019 Mercedes-Benz E450 replaces the previous E400, and signals the addition of 33 horses and 15 lb-ft of torque to the twin-turbocharged 3.0-liter V-6’s engine, which now packs a total of 362 horsepower and 369 lb-ft of torque. All that oomph will be sent rearward on […]
What is reverted gear train?
What is reverted gear train? When the axes of the first gear (i.e. first driver) and the last gear (i.e. last driven or follower) are co-axial, then the gear train is known as reverted gear trainas shown in Fig. What is the purpose of having a gear train in a power transmission system? A transmission […]
How do you find the IMA of a fixed pulley?
How do you find the IMA of a fixed pulley? In general, the IMA = the resistance force, Fr, divided by the effort force, Fe. IMA also equals the distance over which the effort is applied, de, divided by the distance the load travels, dr. What is the mechanical advantage of a fixed pulley? Pulleys […]
Does temperature remain constant in an adiabatic process?
Does temperature remain constant in an adiabatic process? An adiabatic process is a thermodynamic process during which no energy is transferred as heat across the boundaries of the system. As there is no exchange of heat with surroundings, so total heat of the system remains constant. What stays constant in an adiabatic process? Remember adiabatic […]

How do you find the specific weight of mercury?
How do you find the specific weight of mercury? Mass is a property and the SI unit for density is [kg/m3]. The Imperial (U.S.) units for density are slugs/ft3 but pound-mass per cubic foot – lbm/ft3 – is often used….Specific Gravity for some common Materials. Substance Specific Gravity – SG – Mercury 13.59 Nickel 8.73 […]
What is low pressure die casting?
What is low pressure die casting? Low-pressure die casting is a method of production that uses pressure – rather than gravity – to fill molds with molten metal such as aluminum and magnesium. In this process, the holding furnace is located below the cast and the liquid metal is forced upwards through a riser tube […]
What happens when a magnet is inserted into a coil of wire?
What is the purpose of hardness test?
What is the purpose of hardness test? The principal purpose of the hardness test is to determine the suitability of a material for a given application, or the particular treatment to which the material has been subjected. The ease with which the hardness test can be made has made it the most common method of […]
What do you mean by mean effective pressure?
What do you mean by mean effective pressure? The mean effective pressure is a quantity relating to the operation of a reciprocating engine and is a valuable measure of an engine’s capacity to do work that is independent of engine displacement. What is brake mean effective pressure? Brake mean effective pressure (BMEP) is the mean […]
