How do you find an angle with 3 sides? To solve an SSS triangle: use The Law of Cosines first to calculate one of the angles. then use The Law of Cosines again to find another angle. and finally use angles of a triangle add to 180° to find the last angle….In this triangle we […]
What is the precedence of line?
What is the precedence of line? Precedence of Lines Lines are shown on the views in a prescribed order of precedence. A solid line (object or continuous) takes precedence over a hidden line, and a hidden line takes precedence over a centerline. What are the types of lines in engineering drawing? Following are the different […]
How brushless motors are made?
How brushless motors are made? Every brushless motor is made of two main parts, a stator and a rotor. The stator is static, it does not move, and it holds the electromagnets. The rotor is the rotating component that holds the permanent magnets. There are two types of Brushless DC motors: Inrunner and outrunner models. […]
What is belt tensioning?
What is belt tensioning? Belt tension The ideal belt is that of the lowest tension that does not slip in high loads. Belt tensions should also be adjusted to belt type, size, speed, and pulley diameters. Belt tension is determined by measuring the force to deflect the belt a given distance per inch (or mm) […]
What is the Polyval function in Matlab?
Why do bimetallic strips bend?
Why do bimetallic strips bend? A bimetallic strip is made of two separate strips of metal stuck together. These two strips expand to a different extent when heated. So, when the strip is heated, one strip will be longer than the other. Therefore, the bimetallic strip will bend. What determines heat transfer direction? The distribution […]
What is the glass transition temperature of polyethylene?

Glass Transition Temperature Values of Several Plastics Polymer Name Min Value (°C) Max Value (°C) PE – Polyethylene 30% Glass Fiber -110.0 -110.0 PEEK – Polyetheretherketone 140.0 145.0 PEEK 30% Carbon Fiber-reinforced 140.0 143.0 PEEK 30% Glass Fiber-reinforced 143.0 143.0 Can non crystalline materials have glass transition […]
What causes the narrowing of the artery with atherosclerosis?
What causes the narrowing of the artery with atherosclerosis? Once the inner wall of an artery is damaged, blood cells and other substances often clump at the injury site and build up in the inner lining of the artery. Over time, fatty deposits (plaque) made of cholesterol and other cellular products also build up at […]
What are the characteristics of a helicopter?
What are the characteristics of a helicopter? A helicopter is a type of aircraft that uses rotating, or spinning, wings called blades to fly. Unlike an airplane or glider, a helicopter has wings that move. Unlike a balloon, a helicopter is heavier than air and uses an engine to fly. How many types of helicopters […]
How is blood alcohol measured?
How is blood alcohol measured? To calculate BAC, the amount of alcohol in the bloodstream is measured in milligrams (mg) of alcohol per 100 milliliters (ml) of blood. It is usually expressed as a decimal such as 0.08 or 0.15. For example, a BAC of 0.10% means that an individual’s blood supply contains one part […]
