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. […]
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 […]
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 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 […]
How do astronauts train for EVAs?
How do astronauts train for EVAs? One way astronauts train for spacewalks is by going for a swim. Floating in space is a lot like floating in water. Astronauts practice spacewalks underwater in a large swimming pool. The pool is called the Neutral Buoyancy Laboratory, or NBL. Why is a spacewalk exhausting? Because the air […]
What club should I use for 175 yards?
What are the two possible arrangements for a concentric tube heat exchanger for each arrangement what restrictions are associated with the fluid outlet temperatures?
What are the two possible arrangements for a concentric tube heat exchanger for each arrangement what restrictions are associated with the fluid outlet temperatures? What are the two possible arrangements for a concentric tube heat exchanger? For each arrangement, what restrictions are associated with the fluid outlet temperatures? The two possible arrangements would be parallel […]
