How do you test an alternator charging system? The other step to troubleshoot the alternator charging system is to measure the voltage of the battery while the engine is running using a voltmeter for accurate results. If the recorded voltage is higher or equal to 13.8 volts, you can test the alternator output. How long […]
How often do you need to replace car batteries?
How often do you need to replace car batteries? After three years, it’s normally time to install a replacement. After four or five years, most car batteries will be almost completely unreliable. Old car batteries can present a number of safety and reliability issues. Luckily, it’s easy to identify if your car’s battery is nearing […]

Key factors affecting the Brayton cycle efficiency includes the turbine inlet temperature, compressor and turbine adiabatic efficiencies, recuperator effectiveness and cycle fractional pressure loss. Which gas turbine is used in aircraft? Turbofans What is meant by gas turbine? A gas turbine is a combustion engine […]
Why testing can only detect the presence of errors NOT their absence?
Why testing can only detect the presence of errors NOT their absence? 1 Answer. Testing can detect only the presence of errors, not their absence because the main goal of the testing is: to observe the behavior of the particular software and to check whether it meet its requirement expectation or not. Testing is a […]

What is an orthogonal cutting operation?
What is an orthogonal cutting operation? What is an orthogonal cutting operation? Orthogonal cutting involves the use of a wedge-shaped tool in which the cutting edge is perpendicular to the direction of speed motion into the work material. What are the effects of lowering the friction at the tool chip interface on the mechanics of […]
What is the ASTM grain size number?
What is the ASTM grain size number? ASTM grain size number : the ASTM grain size number, G, is defined as : NAE = 2G-1 where NAE is the number of grains per square inch at 100X magnification. Most metals are crystalline in nature and contain internal boundaries, commonly known as “grain boundaries”. Does […]
