Which cycle is the most efficient of these for the same compression ratio a Otto cycle B diesel cycle? Explanation: Otto cycle is more efficient than Diesel cycle for a given compression ratio. 6. For constant maximum pressure and heat input, the air standard efficiency of the gas power cycle is in the order. What […]

What wood joint is the weakest?
What wood joint is the weakest? Butt Joint What is the strongest joining method for wood? Mortise and Tenon Joint The mortise and tenon is a classic wood joinery method. These joints have been used since the early times of woodworking, and are still among the strongest and most elegant methods for joining wood. How […]
What are over damped critically and under damped systems?
What are over damped critically and under damped systems? An overdamped system moves slowly toward equilibrium. An underdamped system moves quickly to equilibrium, but will oscillate about the equilibrium point as it does so. A critically damped system moves as quickly as possible toward equilibrium without oscillating about the equilibrium. What is the effect of […]
How is Froude number calculated?
How is Froude number calculated? It is generally expressed as Fr = v/(gd)1/2, in which d is depth of flow, g is the gravitational acceleration (equal to the specific weight of the water divided by its density, in fluid mechanics), v is the celerity of a small surface (or gravity) wave, and Fr is the […]

What is the difference between E400 and E450?
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 […]
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 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 […]
