Orthographic drawings

Assignment 1:

You must now draw an orthographic view of your completed container.

[lo 1.2]

What is an orthographic drawing?

It is a method of drawing a 3D object correctly as seen from different views. Each view is drawn as if it is a flat surface and in 2D. Usually a shape is drawn from three views, namely the front view, the side view and the overhead top view or plan.

a) Below there are some 3D figures. Next to each one of them there are three shapes. This shows what the objects will look like from the front, the side and from above. Write underneath each 2D figure whether it is the image as seen from the front, from the side or from above.

b) Let’s first practise how to make an orthographic drawing.

Remember:

  • Do it on grid paper.
  • See to it that the length, width and height of the shape are indicated. (Sketch 1).
  • Start with the front view, which is always drawn, in the left-hand top corner.
  • The top view is drawn next in the left-hand bottom corner. (Extend the vertical sides of the front view.)
  • The side view (from the right) is always drawn in the right-hand top corner. (Extend the horizontal sides of the front view.)
  • Each space on the axes represents one cm. Start with the first mark.
  • Halve the remaining space diagonally across the front with a 45˚ diagonal line. Use this line to transfer the lengths from the top view to the side view.
  • Complete all three views and provide the necessary captions.
  • Now also make 2D drawings of the following 3D shapes. First indicate the views relevant to each shape.

Learning Outcomes(LOs)

LO 1

TECHNOLOGICAL PROCESSES AND SKILLS

The learner will be able to apply technological processes and skills ethically and responsibly using appropriate information and communication technologies

Assessment Standards(ASs)

We know this when the learner:

1.2 finds out about existing products relevant to a problem, need or opportunity, and identifies and compares their design aspects (e.g. who it is for, what it is for, what it looks like, what it is made of, how well it works, whether it will affect the environment).

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.

what is the application of nanotechnology?
Stotaw
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google

anybody can imagine what will be happen after 100 years from now in nano tech world
Prasenjit
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
Azam
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
Prasenjit
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
Damian
silver nanoparticles could handle the job?
Damian
not now but maybe in future only AgNP maybe any other nanomaterials
Azam
Hello
Uday
I'm interested in Nanotube
Uday
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
Prasenjit
can nanotechnology change the direction of the face of the world
Prasenjit Reply
At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.
