How should you hold the stock while cutting it with a band saw? Hold stock firmly and flat on the table to prevent the stock from turning and drawing your fingers against the blade. Use a push stick when you remove cut pieces from between the fence and saw blade or when your hands are […]
How does grain size affect the properties of a metal?
How does grain size affect the properties of a metal? Grain size has a measurable effect on most mechanical properties. Also, fine-grain steels have greater fatigue resistance, and a fine grain size promotes a somewhat greater tough- ness and shock resistance. Steels made fine grained by addition of aluminum have machinability inferior to those made […]
Is a refrigerator an open or closed system?
What is the working principle of Venturi meter?
What is the working principle of Venturi meter? The principle behind the operation of the Venturi flowmeter is the Bernoulli effect. The Venturi measures a fluid’s flowrate by reducing the cross sectional flow area in the flow path and generating a pressure difference. What is Venturimeter explain its construction and working? Venturimeter is work on […]

Nuclear Power. Hydroelectric Energy. Wave Energy. Biofuels. Natural Gas. Geothermal Power. Wind Energy. What is the three basic energy system? During exercise, your […]
How many ways can you separate mixtures?
How many ways can you separate mixtures? 1 Answer. mixtures can be separated using various separation methods such filtration,separating funnel,sublimation,simple distillation and paper chromatography. How do you separate mixtures for kids? Another common separation process is called distillation. Distillation uses boiling to separate mixtures of liquid solutions. It takes into account that different substances in […]
What is the formula for calculating efficiency?
What is the formula for calculating efficiency? The formula to calculate work efficiency is the ratio of output to input expressed as a percentage. The work efficiency formula is efficiency = output / input, and you can multiply the result by 100 to get work efficiency as a percentage. How do you calculate the maximum […]
What does a negative angular acceleration indicate to you?
What does a negative angular acceleration indicate to you? Negative angular velocity(ω) means that the particle is revolving anticlockwise. Thus, negative angular acceleration(α) is a “push” in the anticlockwise direction. If α and ω have the same sign, the body will speed up, else slow down (and eventually go in reverse). Is clockwise positive or […]
