What do scientists work to answer questions about? Scientists find answers using tests: When scientists want to answer a question, they search for evidence using experiments. An experiment is a test to see if their explanation is right or wrong. Evidence is made up of the observations a scientist makes during an experiment. What are […]
What is preventive and predictive maintenance?
What is preventive and predictive maintenance? Preventive maintenance (PM) is work that is scheduled based on calendar time, asset runtime, or some other period of time. Predictive maintenance (PdM) is work that is scheduled as-needed based on real time conditions of assets. What is the component required for predictive maintenance? Some of the main components […]
How do you measure strain with strain gauge?
How do you measure strain with strain gauge? Therefore, to measure the strain, you have to accurately measure very small changes in resistance. For example, suppose a test specimen undergoes a strain of 500 me. A strain gage with a GF of 2 exhibits a change in electrical resistance of only 2 (500 x 10-6) […]
What happens when the base current of a transistor is increased?
What happens when the base current of a transistor is increased? Fundamentally, it is the voltage across the B-E junction that determines the amount of current flowing through it. An increase in this voltage results in increased currents in both the base and the collector, and indeed, an increase in base current causes an increase […]
Why is it important to learn about scientific discoveries?
Why is it important to learn about scientific discoveries? Scientific knowledge allows us to develop new technologies, solve practical problems, and make informed decisions — both individually and collectively. Because its products are so useful, the process of science is intertwined with those applications: New scientific knowledge may lead to new applications. Why do engineers […]

What does it mean when the temperature warning light comes on?
What does it mean when the temperature warning light comes on? When the coolant temperature warning light goes on, the engine is seriously overheated, which can be caused by overheating, lack of cooling water or a cooling system that is having trouble. At this point, you need to park your car in a safe area […]
Can I build house without pillar?
What is the name of piping system adopted in plumbing of drainage?
What is the name of piping system adopted in plumbing of drainage? Single Stack System This system of pipes carries waste water from the wash basin, bathrooms, sinks and the foul matters from the water closets. This is connected to a final single pipe. Is a drain from the two or three fixtures connected to […]
What is the driving force for recrystallization?
What is the driving force for recrystallization? The main driving force for recrystallization to occur is the stored energy during straining in the form of crystalline defects. In a region exempt of defects, surrounded by high angle boundaries, recrystallization proceeds by growth of this “nucleus” over the yet non-recrystallized matrix. How does cold working affect […]
