How do you determine bearing size for shaft?

How do you determine bearing size for shaft? 1) If the load will be mostly radial (perpendicular to the shaft), use a radial bearing, and if the load will be mostly axial* (same direction as the shaft), use a thrust bearing. * Axial loads are sometimes called thrust loads. Which bearing can take radial load […]

Is a steam engine a heat engine?

Is a steam engine a heat engine? A steam engine is a heat engine that performs mechanical work using steam as its working fluid. Steam engines are external combustion engines, where the working fluid is separated from the combustion products. The ideal thermodynamic cycle used to analyze this process is called the Rankine cycle. Is […]

What artery in the body has the largest diameter?

What artery in the body has the largest diameter? In the systemic circuit, blood is ejected out of the left ventricle via a single large artery—the aorta. All arteries of the systemic circulation branch from the aorta (this is the largest artery of the body, with a diameter of 2-3 cm), and divide into progressively […]

What is the difference between crystalline and noncrystalline structures in materials?

What is the difference between crystalline and noncrystalline structures in materials? The most basic difference between crystalline solids and noncrystalline solids (NCS) is that a long-range order in the distribution of atoms (ions) or molecules exists in the first case but not in the second. Any real suhstance, including noncrystalline material, is inhomogeneous regardless of […]

How would you manufacture a hammer head?

How would you manufacture a hammer head? The head is made by a process called hot forging. A length of steel bar is heated to about 2,200-2,350° F (1,200-1,300° C) and then die cut in the shape of the hammer head. Once cut, the hammer head is heat treated to harden the steel. What are […]

How do you measure alcohol content in gasoline?

How do you measure alcohol content in gasoline? Take a reading where the water and alcohol separate. If there is no alcohol in the gasoline, you’ll see the separation at the two milliliter mark, which is the amount of water that you started with. If the separation line is above the two milliliter mark, you […]
