How does a strain gauge sensor work? A Strain gauge is a sensor whose resistance varies with applied force; It converts force, pressure, tension, weight, etc., into a change in electrical resistance which can then be measured. When external forces are applied to a stationary object, stress and strain are the result. What is the […]
What is the length of a pendulum with a period of 2 seconds?
What is the length of a pendulum with a period of 2 seconds? Using the SI recommended acceleration due to gravity of g0 = 9.80665 m/s2, the length of the string will be approximately 993.6 millimetres, i.e. less than a centimeter short of one metre everywhere on Earth. How do you calculate the period of […]
How are the engineering design process and the scientific method similar?
How are the engineering design process and the scientific method similar? While scientists study how nature works, engineers create new things, such as products, websites, environments, and experiences. Scientists perform experiments using the scientific method; whereas, engineers follow the creativity-based engineering design process. What are the similarities between science and engineering? Like science, engineering covers […]
How can you tell the difference between a series circuit and a parallel circuit?
How can you tell the difference between a series circuit and a parallel circuit? In a series circuit, a common current flows through all the components of the circuit. While in a parallel circuit, a different amount of current flows through each parallel branch of the circuit. In the series circuit, different voltage exists across […]
What are the causes of turbocharger failure?
What are the causes of turbocharger failure? Most failures are caused by the three ‘turbo killers’ of oil starvation, oil contamination and foreign object damage. More than 90% of turbocharger failures are caused oil related either by oil starvation or oil contamination. Blocked or leaking pipes or lack of priming on fitting usually causes oil […]
What is difference between l2 switch and l3 switch?
What is difference between l2 switch and l3 switch? A Layer 2 switch only works with MAC addresses and doesn’t interact with any higher layer addresses, such as an IP. A Layer 3 switch, on the other hand, can also do static routing and dynamic routing, which includes IP and virtual local area network (VLAN) […]
What is error and types of error?
What is error and types of error? Errors are normally classified in three categories: systematic errors, random errors, and blunders. Systematic Errors. Systematic errors are due to identified causes and can, in principle, be eliminated. Errors of this type result in measured values that are consistently too high or consistently too low. What are the […]
Which of the following will not disqualify your vehicle from being used?
Which of the following will not disqualify your vehicle from being used? According to that and considering the options given, the one that will not disqualify you car is a crack in your windshield that doesn’t affect visibility. What is a Florida Class E drivers license? CLASS E: Any non-commercial motor vehicles with Gross Vehicle […]
How are superalloys made?
How are superalloys made? Many superalloys are produced using a two-phase heat treatment that creates a dispersion of cuboidal γ’ particles known as the primary phase, with a fine dispersion between these known as secondary γ’. These elements form the base matrix γ phase of the superalloy. Ni is necessary because it also forms γ’ […]
What types of evidence can be collected at a crime scene?
What types of evidence can be collected at a crime scene? Samples That May be Collected at a Crime Scene biological evidence (e.g., blood, body fluids, hair and other tissues) latent print evidence (e.g., fingerprints, palm prints, foot prints) footwear and tire track evidence. trace evidence (e.g., fibers, soil, vegetation, glass fragments) What are the […]
