What three things drive a roller coaster?
What three things drive a roller coaster? Roller coasters rely on gravity to take them to the end of the track. This involves two types of energy, potential energy and kinetic energy. Who invented roller coasters? LaMarcus Thompson What makes a good roller coaster? A great roller coaster has what one would call good pacing. […]
How often does rigid conduit need to be supported?
How often does rigid conduit need to be supported? Shall be securely fastened within 3 feet of a box, conduit body, or other point of termination. Support shall comply with Table 352.30, based on the size of the conduit. Shall be secured and fastened within 3 feet of a box, conduit body, or other point […]
What does a tensile test determine?
What does a tensile test determine? A tensile test applies tensile (pulling) force to a material and measures the specimen’s response to the stress. By doing this, tensile tests determine how strong a material is and how much it can elongate. What is the relationship between tensile strength and elongation? The force at material rupture […]
What is the use of reheat cycle in steam turbine?
What is the use of reheat cycle in steam turbine? The purpose of a reheating cycle is to remove the moisture carried by the steam at the final stages of the expansion process. In this variation, two turbines work in series. Why Carnot cycle is practically not possible? This means that the Carnot cycle is […]
What process is spot welding?
What process is spot welding? Spot welding (also known as resistance spot welding) is a resistance welding process. This welding process is used primarily for welding two or more metal sheets together by applying pressure and heat from an electric current to the weld area. What is hold time in spot welding? Hold time is […]
What type of magnet attracts iron?
What type of magnet attracts iron? Ferromagnetic materials such as iron, nickel and cobalt are therefore attracted to magnets, as well as rare-earth metals like gadolinium, neodymium and samarium. Can a magnet attract iron? Magnetic Field, Magnetic Field, 1) When two magnets are brought near each other, like poles repel; opposite poles attract. 2) When […]
What is Fe2O3 xH2O?
What is Fe2O3 xH2O? Fe2O3. xH2O is usually called hydrated ferric Oxide. It is a hydrated crystal. When Ferrous ion forms an ionic bond with Oxygen, it is called Ferrous Oxide. What are the conditions required for rusting? Rusting is an oxidation reaction. The iron reacts with water and oxygen to form hydrated iron(III) oxide, […]
What is ductile and brittle failure?
What is ductile and brittle failure? Brittle Fracture involves fracture without any appreciable plastic deformation (i.e. energy absorption). Ductile Fracture in the converse and involves large plastic deformation before separation. The difference between brittle and ductile fracture is illustrated in figures 1 and 2. What type of failure is exhibited by a brittle material behave […]
