hallo people just registerd here because ive got some college questions im stuck on. im doing a carpentry course by the way.
right ...
q1 is (what is the advantage of using tct tools?)
q2 is (name two factors that govern the spacing or centres of upper floor joists)
q3 is (state two purposes of a specification)
q4 is (explain briefly what is meant by first angle orthographic projection)
tanks for all your help people :thumbsup:
no doubt ill be back:laughing:

Ya know, the problem with homework is if you don't do it yourself, you won't learn from it.

Double A is right... on the other hand... if you don't ask so direct... like people doing the homework for you and you go out to date that other woman in the corner... you would get some answers... try ask it like you did do some work... and just won't be able to do some even you try hard.... I am sure you know what I meant... not that people here is so moral... it just makes people feel dump to help answer questions like that...

now for the fun part, trying to be back on my 20's, I don't know answers of any of the questions, but this one I can give it a try:

q3 is (state two purposes of a specification)

purpose 1 - a specification can help to ensure a standard is being met or not, without it, people cannot measure the standard of what is being built.

purpose 2 - it help to measure the value of a product/material... as the different specifications can associate with different cost involves...

No doubt you're suppose to either be answering from your notes, hand outs or a textbook. While you'll get many good answers here they may even be right lol but they may not be THE answers your professor is looking for.

that being said...
a1 less sawdust, less power consumption, more precise cuts, less wasted wood.
a2 span and whether or not any roof load is transferred via load bearing walls to those joists
a3 specs can define the grade of products which guarantees their quality and strength is in a certain range. Specifying an item is used to control cost, design integrity and fitment.
a4 this is the standard three 2d view projection of a 3d object by rotating the lines of site 90 degrees. For blueprints this is standard front, side and top (or plan) views are drawn so the blueprint reader can picture the object in 3d. see here http://en.wikipedia.org/wiki/Orthographic_projection

Enjoy school while you can and LEARN!

(But what if he's wrong....?)

I new number two. I was going to say span and Weight. Weight being defined as larger weight will need reinforcement.

For number 3 i could only think of tolerance.

:laughing:

If by TCT tools , you mean Tungsten Carbide tipped; then a couple of other advantages are:
Longer power tool life (it doesn't work as hard)
Better finish quality
The ability to machine a variety of materials.
Perhaps more importantly, longer cutting tool life, and the ability to resharpen multiple times (depending on the thickness of
the Tungsten Carbide tips.

Compliance with stated specifications "should" ensure the quality of the finished product.
Specifications define three primary things:
What material is to be used (approved content, approved source, and approval body)
How it is to be installed (methods, type, number, and location of fasteners etc.)
The tolerances (dimensional, material, chemical etc.) are the ALLOWED variation from the nominal specification.

The word "Orthographic" is derived from two Greek words: orthos, meaning straight, correct, at right angles to; and graphikus, meaning to write or describe by drawing lines. The third angle projection commonly used in the U.S. can be pictured thusly:
a lowercase "letter" "T" lying on its left side composed of six connected boxes the leftmost (left side view), to its right (front view), above (top view) below (bottom view), to its right(right side view), and finally to the right end(rear view). The above is loosel paraphrased from Engineering Drawing and Design Second Edition by Cecil Jensen/Jay Helsel McGraw-Hill 1979
Pardon the detail, hope this helps.
