What causes clear cutting? Soil erosion is caused by poorly laid out road systems, whether or not the forest is clearcut or only partially cut. Clearcutting can be done without significant erosion or sedimentation if roads are pre-planned and built correctly by using accepted Best Management Practices to protect streams. What are the pros and […]

The following are seven welding careers you may not have thought of: Assemblers and Fabricators: Boilermakers: Jeweler, Precious Stone, and Metal Workers: Machinists, Tool, and Die Makers: Sheet Metal Workers: Plumbers, Pipefitters, and Steamfitters: Metal and Plastic Machine Workers: How do you protect yourself from welding fumes? How can […]

What is the most common cause of scored brake drums? Scored Brake Drums This condition is caused by interference between the hub and drum mounting surface during installation as a result of using the wrong drum for the application or improperly cleaning the hub piloting surface prior to drum installation. What causes brake drums to […]

Why FET is called field effect transistor? Field effect transistors (FETs) work on a pricipal that uses the field produced by the gate in a way that makes the channel conduct more or less. The FET was named such because the of how the static field, as apposed to current, plays a central role in […]

Which welding processes generate less heat affected zone? With regard to welding procedures, those processes with low heat input will cool faster, leading to a smaller HAZ, whereas high heat input will have a slower rate of cooling, leading to a larger HAZ in the same material. In addition, the size of the HAZ also […]

How do you increase the efficiency of a steam power plant? Tips to improve steam plant efficiency Step 1: Do a Steam Trap Survey. First, a steam trap survey can easily identify leaking or faulty traps and provide significant potential savings. Step 2: Understand the Value of Condensate. Step 3: Insulate your Steam System. Step […]

What is absorption in simple words? Absorption is a condition in which something takes in another substance. It is a physical or chemical phenomenon or process, in which atoms, molecules, or ions enter in the inner part (called “bulk”) of a gas, liquid, or solid material. What does absorption mean? 1a : the process of […]

Examples: Turning left and turning right are Mutually Exclusive (you can’t do both at the same time) Tossing a coin: Heads and Tails are Mutually Exclusive. Cards: Kings and Aces are Mutually Exclusive. Which two events are mutually exclusive? In statistics and probability theory, two […]

What is the maximum principal stress in a thin cylinder? The maximum principal strain in a thin cylindrical tank, having a radius of 25 cm and wall thickness of 5 mm when subjected to an internal pressure of 1MPa, is (taking Young’s modulus as 200 GPa and Poisson’s ratio as 0.2) 2.25 × 10. 2.25. […]
