How do you determine cutting speed? Formula to determine feed rate FR = the calculated feed rate in inches per minute or mm per minute. RPM = is the calculated speed for the cutter. T = Number of teeth on the cutter. CL = The chip load or feed per tooth. This is the size […]
How is creep calculated?
How is creep calculated? Creep testing is conducted using a tensile specimen to which a constant stress is applied at a constant temperature, often by the simple method of suspending weights from it. The test is recorded on a graph of strain versus time. What are the 3 stages of creep? Creep occurs in three […]
What is load factor and demand factor?
What is load factor and demand factor? The connected load is always known so it will be easy to calculate the maximum demand if the demand factor for a certain supply is known at different time intervals and seasons. The lower the demand factor, the less system capacity required to serve the connected load. How […]
How do you isolate a circuit?
How do you isolate a circuit? To isolate a circuit, you need to terminate the flow of electricity through it. Decide whether you want to isolate a complete circuit or a particular electrical appliance. Flip the trip switch or remove a fuse in your fuse box by hand if you want to completely isolate a […]
Does hash algorithm provide integrity?
Does hash algorithm provide integrity? A hash function does not provide integrity! posted April 2017. A hash function does not provide integrity, a MAC provides integrity. Instead a cryptographic hash function provides three properties, well defined in the world of cryptography: collision resistance, pre-image resistance and second pre-image resistance. Why does a hash function used […]
Where should the compressed gas and fuel cylinders be stored?
Where should the compressed gas and fuel cylinders be stored? The gas cylinders should be stored in a cool, dry, well-ventilated, fire-resistant area that meets all applicable federal, state and local regulations. When a gas cylinder is empty or not being used, ensure that the valve is closed, the regulator removed and the valve protector […]
How do you measure current through a resistor?
Does higher octane gas burn faster?
Does higher octane gas burn faster? Higher octane gasoline reduces knocks and pings in high-pressure environments which exert more energy and burn fuel quicker. Does premium gas burn faster than regular? The main difference with premium is its octane rating — 91 or higher compared with 87 for regular octane. The higher octane of premium […]
What are the environmental impacts of renewable energy?
What are the environmental impacts of renewable energy? The environmental impacts associated with solar power can include land use and habitat loss, water use, and the use of hazardous materials in manufacturing, though the types of impacts vary greatly depending on the scale of the system and the technology used—photovoltaic (PV) solar cells or concentrating […]
How is thermal efficiency of Otto cycle calculated?
How is thermal efficiency of Otto cycle calculated? When we rewrite the expression for thermal efficiency using the compression ratio, we conclude the air-standard Otto cycle thermal efficiency is a function of compression ratio and κ = cp/cv. What is the formula for compression ratio of the Otto cycle? For example, let assume an Otto […]
