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 […]

What are the load factors of dead load and live load? Load combinations For example, in designing a staircase, a dead load factor may be 1.2 times the weight of the structure, and a live load factor may be 1.6 times the maximum expected live load. What is the LRFD method? Load and Resistance Factor […]

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. […]

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 […]
