How do you find the maximum bending stress of a beam? The maximum shear stress occurs at the neutral axis of the beam and is calculated by: where A = b·h is the area of the cross section. Note that the maximum shear stress in the cross section is 50% higher than the average stress […]
What happens if an engine runs too cool?
What happens if an engine runs too cool? When an engine runs cold so does its lubricating oil, which means more potential for moisture and acid to form in its oil. At higher temps (both oil and engine) harmful deposits are boiled off. When an engine runs too cold, the fuel economy goes down, often […]
How do you calculate tractive effort?
How do you calculate tractive effort? Tractive effort and Resistance to motion The maximum speed can roughly be calculated by reading the point at which tractive effort = resistance to motion on the graph. We can then solve this cubic through various methods to get Speed=58.03m/s. That’s 208.9kph or 129.8mph! How do you calculate the […]
What is the value of n in Polytropic process?
What is the value of n in Polytropic process? The expansion of the gaseous products of a high explosive can be modeled as a polytropic process. In the high pressure regime, n approximately equals to 3. The value of n decreases with the expansion of the products, and finally approaches 1.4 when the products expand […]
Does salt help water boil?
Does salt help water boil? When salt is added, it makes it harder for the water molecules to escape from the pot and enter the gas phase, which happens when water boils, Giddings said. This gives salt water a higher boiling point, she said. “The temperature of saltwater will get hotter faster than that of […]
What happens when a switch in a circuit is opened?
What happens when a switch in a circuit is opened? A device designed to open or close a circuit under controlled conditions is called a switch. The terms “open” and “closed” refer to switches as well as entire circuits. An open switch is one without continuity: current cannot flow through it. Can a current flow […]
What tool is used in combination with an impact wrench to install lug nuts on wheels?
What tool is used in combination with an impact wrench to install lug nuts on wheels? n impact wrench (also known as an impactor, impact gun, air wrench, air gun, rattlegun, torque gun, windy gun) is a socket wrench power tool designed to deliver high torque output with minimal exertion by the user, by storing […]
How do you politely ask for something urgent?
How do you politely ask for something urgent? ‘As Soon As Possible’ Synonyms “… by [date and time] because [reason]” “When you have a chance [in the next day, before tomorrow, this week]” “I apologize for the urgency, but could you please [do X, send me Y, complete Z] at your soonest possible convenience?” “EOD” […]
What can a temperature sensor be used for?
What can a temperature sensor be used for? A temperature sensor is an electronic device that measures the temperature of its environment and converts the input data into electronic data to record, monitor, or signal temperature changes. There are many different types of temperature sensors. What are types of temperature Sensors? There are four types […]
