Is it easy to replace a rear derailleur? Believe it or not, it’s not difficult to replace the rear derailleur yourself. Unscrew the derailleur from the derailleur hanger by inserting a hex wrench and turning counter-clockwise. The derailleur will now come away from the hanger. Remove the derailleur cable by loosening the hex bolt on […]
How do you identify process improvements?
How do you identify process improvements? 4 Steps for an Effective Business Process Improvement Cycle Identify the need for change: The first step in the BPI process is to identify the need for change. Analyze current process: Once you have decided which process you are going to improve you need analyze the current procedure. Obtain […]
What does the stator do in an alternator?
What does the stator do in an alternator? The stator is fixed to the shell of the alternator, and does not turn. As the rotor turns within the stator windings, the magnetic field of the rotor sweeps through the stator windings, producing an electrical current in the windings. Because of the rotation of the rotor, […]
What are the strokes of a 4 stroke cycle?
What are the strokes of a 4 stroke cycle? An internal-combustion engine goes through four strokes: intake, compression, combustion (power), and exhaust. How many of the 4 strokes turn the engine? 2 How many times for every 4 strokes in a 4 stroke engine cycle does the crankshaft rotate? A 4-stroke engine fires once every […]
What is Fe2O3 xH2O?
What is Fe2O3 xH2O? Fe2O3. xH2O is usually called hydrated ferric Oxide. It is a hydrated crystal. When Ferrous ion forms an ionic bond with Oxygen, it is called Ferrous Oxide. What are the conditions required for rusting? Rusting is an oxidation reaction. The iron reacts with water and oxygen to form hydrated iron(III) oxide, […]
What is ductile and brittle failure?
What is ductile and brittle failure? Brittle Fracture involves fracture without any appreciable plastic deformation (i.e. energy absorption). Ductile Fracture in the converse and involves large plastic deformation before separation. The difference between brittle and ductile fracture is illustrated in figures 1 and 2. What type of failure is exhibited by a brittle material behave […]
What type of work do construction workers do?
What type of work do construction workers do? Construction workers (also known as construction laborers) work on construction sites. They are responsible for a number of on-site tasks, such as removing debris, erecting scaffolding, loading and unloading building materials, and assisting with operating heavy equipment. What is the work environment like for a construction worker? […]
What is the latent heat of vaporization for water latent heat?
What is the latent heat of vaporization for water latent heat? The heat of vaporization of water is about 2,260 kJ/kg, which is equal to 40.8 kJ/mol. The vaporization is the opposite process of condensation. The heat of condensation is defined as the heat released when one mole of the substance condenses at its boiling […]
What does a tensile test determine?
What does a tensile test determine? A tensile test applies tensile (pulling) force to a material and measures the specimen’s response to the stress. By doing this, tensile tests determine how strong a material is and how much it can elongate. What is the relationship between tensile strength and elongation? The force at material rupture […]
What is the use of reheat cycle in steam turbine?
What is the use of reheat cycle in steam turbine? The purpose of a reheating cycle is to remove the moisture carried by the steam at the final stages of the expansion process. In this variation, two turbines work in series. Why Carnot cycle is practically not possible? This means that the Carnot cycle is […]
