What is hoop stress in thick cylinder? In mechanics, a cylinder stress is a stress distribution with rotational symmetry; that is, which remains unchanged if the stressed object is rotated about some fixed axis. circumferential stress, or hoop stress, a normal stress in the tangential (azimuth) direction. Where does the maximum hoop stress in a […]

How do you find the hydraulic diameter of a rectangular duct?
How do you find the hydraulic diameter of a rectangular duct? The hydraulic diameter is four times the flow area divided by the duct perimeter. The formulas given before show the diameter d. For rectangular and oval ducts, a corrected hydraulic diameter should be used. What is meant by hydraulic diameter? The hydraulic diameter (aka […]
What type of simple machine is a screw?
What type of simple machine is a screw? A screw is a special kind of inclined plane. It’s basically an inclined plane wrapped around a pole. Screws can be used to lift things or to hold them together. Examples of the screw simple machine include swivel chairs, jar lids, and, of course, screws. Is a […]
How are molds made for injection molding?
How are molds made for injection molding? Injection molds, which are usually made from steel, contain cavities that will form the parts. Melted plastic is injected into the mold, filling the cavities. The mold is cooled, and the parts are ejected by pins. This process is similar to a jello mold which is filled then […]
What are degreasers made of?
What are degreasers made of? One active ingredient in many degreasers, sodium carbonate (also known as soap ash), is used in powdered detergents as well as degreasers. Sodium carbonate works to break down grease and oil, and remove lubricants from materials and objects. What are degreasers used in cleaning? A degreaser is a cleaner designed […]
Should blood flow be laminar or turbulent?
Should blood flow be laminar or turbulent? Generally in the body, blood flow is laminar. However, under conditions of high flow, particularly in the ascending aorta, laminar flow can be disrupted and become turbulent. When this occurs, blood does not flow linearly and smoothly in adjacent layers, but instead the flow can be described as […]
How do you measure toe alignment?
How do you measure toe alignment? Assuming that the steering wheel is already centered, adjust the tie-rods on each side the same amount. Roll the vehicle back and forth several feet a few times to transfer your adjustment to the tires, then re-measure the toe. Repeat this step until the toe is within spec. Does […]
