What is the coefficient of X? A number used to multiply a variable. Example: 6z means 6 times z, and “z” is a variable, so 6 is a coefficient. Variables with no number have a coefficient of 1. Example: x is really 1x. Sometimes a letter stands in for the number. What is the coefficient […]
What is vertical position in welding?
What is vertical position in welding? A “vertical weld” is defined as a weld that is applied to a vertical surface or one that is inclined 45 degrees or less (fig. 7-35). Welding on a vertical surface is much more difficult than welding in the flat or horizontal position due to the force of gravity. […]
What are the requirements for heat transfer to occur?
What are the requirements for heat transfer to occur? Heat can travel from one place to another in three ways: Conduction, Convection and Radiation. Both conduction and convection require matter to transfer heat. If there is a temperature difference between two systems heat will always find a way to transfer from the higher to lower […]
How do you calculate gravitational potential energy?
How do you calculate gravitational potential energy? Show that the gravitational potential energy of an object of mass m at height h on Earth is given by PEg = mgh. How do you find height with potential energy and mass? The formula for potential energy depends on the force acting on the two objects. For […]
How do you calculate the shear force of a beam?
What is encryption techniques?
What is encryption techniques? Encryption is the method by which information is converted into secret code that hides the information’s true meaning. In computing, unencrypted data is also known as plaintext, and encrypted data is called ciphertext. The formulas used to encode and decode messages are called encryption algorithms, or ciphers. What is encryption used […]
What is the equation of the line with an X intercept of and ay intercept of 1?
How is the information revolution different from the industrial revolution?
How is the information revolution different from the industrial revolution? The easiest change to spot is the level of specialisation that the average role requires. The Industrial Revolution created modern industry as we understand it today. The Information Revolution has pushed individuals to become highly specialised in how they contribute to bigger industrial efforts. Why […]
What is the probability that a card randomly drawn from a standard deck of 52 cards is not a king?
Which carbide is used for cutting tools?
Which carbide is used for cutting tools? Cemented carbide What are the two major groups of carbides used for machining? The two groups used for machining are tungsten carbide and titanium carbide, both types may be coated or uncoated. Tungsten carbide particles (1 to 5 micro-m) are are bonded together in a cobalt matrix using […]
