What are the characteristics of a hydraulic system? Characteristics of a Good Hydraulic Fluid Viscosity. Viscosity is a measure of a hydraulic fluid’s resistance to flow. Compressibility. Compressibility is a measure of the amount of volume reduction due to pressure. Wear Resistance. Oxidation Stability. Thermal Stability. Filterability. Rust and Corrosion Protection. Foam Resistance. What is […]
What type of lubricant is used on bearing?
What type of lubricant is used on bearing? A lithium-based grease, whose base oil is mineral oil, is commonly used as a lubricant for rolling bearings, as it is compatible with the working surface of the bearing. How are bearings lubricated? The air/oil method of lubrication, also known as the oil-spot method, uses a similar […]

Does multithreading always provide better performance than single-threaded system?
Does multithreading always provide better performance than single-threaded system? Threading is about taking advantage of idle resources to handle more work. If you have no idle resources, multi-threading has no advantages, so the overhead would actually make your overall runtime longer. For example, if you have a collection of tasks to perform and they are […]

What is horizontal position in welding? The welding position in which the weld is on the upper side of an approximately horizontal surface and against an approximately vertical surface. What are the position of welding? What Is a Welding Position? Flat position. Also referred to as a “downhand” position, the flat position weld is the […]
Which polymer is used in controlled drug release?
Which polymer is used in controlled drug release? Degradable polymers (Figure 2) are attractive materials for the design of drug delivery systems, tissue-engineering scaffolds, implants, and surgical materials. PLGA is the most utilized of the degradable polymers, due its long history of clinical use and favorable controlled-release and degradation behavior. How can Polymers be used […]
What does the area under a velocity vs time graph represent?
What does the area under a velocity vs time graph represent? The area under a speed-time graph represents the distance travelled. This is a velocity time graph of an object moving in a straight line due North. The displacement of this object is the area of the velocity time graph. A sloping line on a […]

Cluster Analysis. Factor Analysis. Latent Class Analysis (LCA) Multidimensional Scaling (MDS) What are the requirements of cluster analysis? The main requirements that […]
Which of the following are employers required to do under OSHA quizlet?
Which of the following are employers required to do under OSHA quizlet? OSHA requires employers to: Maintain conditions and adopt practices reasonably necessary to protect workers on the job.

Why do popcorn kernels pop at different times?
Why do popcorn kernels pop at different times? Now, the answer: The kernels with a higher amount of water in them, when heated, have more steam to expand, and thus reach the ultimate tensile strength of the shell faster. There is also some variability in the tensile strengths of the shells, which lead to some […]
