How do you calculate the plimsoll load line of a boat?
the plimsoll line tells you when youve reached the loading limit on the ship(gross weight). Say its 20 000 tonnes, then youve displaced 20 000 tonnes of water (archemides principle). Where this equates to the water line on the hull
is the plimsoll line. Variation due to water density and temperature will also be taken into account
How to draw U Bolt in autocad?
If in 2D: Step1: Figure out what size pipe your 'U' bolt will encompass, then draw a circle with the same diameter as the pipe it will go around. From two opposite quadrants of the circle draw a line extending in the same direction (these will be the threaded portions - so you must know how long those are to be). Trim the unnecessary portion of the circle, and join all three segments using the PEDIT command. Step 2: Figure out the diameter of your bolt, and offset the joined line that distance. From there, you will have to draw the threaded portion (diagonal lines). If in 3D: Use Step 1 from the 2D process ... Step 2: Extrude a circle, the same diameter of your bolt along the path created by the polyline This will get you started - there can be many more steps, depending on how much detail you are trying to achieve. ~ M.

What is MCU and MCU development?
A MCU is a electronic micro chip that can be programmed to control appliances in the outside world, it can control lights, motors and all kinds of electrical and electronic appliances like opening doors, controlling surveillance cameras, analog to digital conversion and many more. With one MCU, one can do the work of many other electronic components and logic chips, The 8-bit PIC® microcontroller solutions feature a powerful architecture, flexible memory technologies, comprehensive easy-to-use development tools, comprehensive application notes, complete technical documentation and post design-in support through a worldwide sales and distribution network. Microchip is committed to easy migration across product families, providing seamless program memory expansion, pin compatibility, and a unified development environment for all products
Which universities in US are offering masters degree in cad-cam?

chain dimensioning as opposed to datum dimensioning.
chain dimensioning:
4 holes in line on a drawing, first hole position dimensioned from the edge,
remainder dimensioned from the centre of the previous hole.
datum dimensioning:
all holes dimensioned from the edge.
the cumulative tolerance build up on the chain dimensioning allows for greater overall tolerance build up.

Usage of semaphor in operating system?
When several process are running at a time in the operating system there is always a chance of hanging, semaphor helps out OS system in solving out such problem.
Semaphore is just like set of rules that help out multi-process running on a OS to use a resource.The process management under the OS is actually made on the basis of semaphor only.
What is minimum size of a segment in Intel 8086 Why?
In 8086 microprocessor the total memory addressing capability is 1 mega bytes. For representing 1 mb there are minimum 4 hex digits are required i.e, 20 bits. but 8086 has fourteen 16-bit registers. That is there are no registers for representing 20 bit address. So,the total memory is divided into 16 logical segments and each segment capacity is 64 kb(kilo bytes). That is 16*64kb=1 mb.So,for representing 64 kb only 16 bit register is sufficient. In 8086 microprocessor the total memory addressing capability is 1 mega bytes.

How do you yank and paste lines in UNIX?
The command 'Y' or 'yy' copies (yanks) one or more lines. To copy one line, two lines, 10 lines, and all lines to the end of the file, respectively:
Y
2Y
10Y
yG
To paste the text contained in the buffer above (uppercase P) or below the current cursor position (lowercase p), respectively:
P
p
It is also possible to yank text within a line. The following commands yank text from the current cursor position to the end of the word and the end of the line, respectively:
yw
y$
The same commands paste the text within a line. Lower case p pastes after the cursor position and upper case P pastes before.
Paste will also work with deleted text, either lines or parts of lines. Be careful not to execute any other commands prior to pasting as this will empty the buffer.
