Answer:
V = 125.7m/min
Explanation:
Given:
L = 400 mm ≈ 0.4m
D = 150 mm ≈ 0.15m
T = 5 minutes
F = 0.30mm ≈ 0.0003m
To calculate the cutting speed, let's use the formula :
We are to find the speed, V. Let's make it the subject.
Substituting values we have:
V = 125.68 m/min ≈ 125.7 m/min
Therefore, V = 125.7m/min
Answer:
K
Explanation:
For installations where the nonlinear load is huge, most consulting engineers will specify K-rated transformers.
Any collection of data or information that has been properly structured for quick search and retrieval by a computer is referred to as a database, often known as an electronic database.
<h3>What is electronic database?</h3>
- Databases are designed to make it easy to save, retrieve, edit, and delete data while carrying out various data-processing tasks. In response to queries, a database management system (DBMS) retrieves data from the database.
- Databases are briefly discussed after that. See computer science: Information systems and databases; information processing for a comprehensive explanation.
- A file or collection of files used to store a database.
- These files' contents can be divided up into records, each of which has one or more fields.
- The fundamental units of data storage are fields, and each field typically contains data related to one feature or attribute of the thing that the database is describing.
- Additionally, records are arranged into tables that contain details on the connections between their various fields.
- A database in the strict sense offers cross-referencing capabilities, despite the fact that the term "database" is used broadly to refer to any collection of information in computer files.
- Users can quickly search, rearrange, organize, and choose the fields in numerous records to access or produce reports on certain data aggregates using keywords and a variety of sorting instructions.
