i want to know, can a diploma in civil engineer with an experience of 10 years working in a structural engineering company and exposure to structural engineering by designing several apartments, commercial complex , give structural designs and can do private practice? or it is an offence or illegal? Because so many builders can build apartments, buildings without knoweldge of any engineering degree but only on their expericence also an ordinary bar bender will give steel details for a residence, can't a civil diploma holder with design experience? or is there is any other way to become structural engineer by short term CERTIFICATE course except the AMIE or Me(struct) Can anybody help me out as early as possible. Beacause I'm frustated by age.

What do you guys think of the moon landing being staged. I did alot of reading and its seems very possible. Such points include the technology not being available, the flag waving with no wind,( photos taken from areas where there was no photogropher) More photos were takin then would have been possible in the amount of time they spent on the "moon"
What do you think,? A lot of people have trouble coming to terms with such allegations and will refuse to Acknowledge any possibility.

Recently I ran across a math term and now I've forgotten it.

What is the term used for objects that you can fit together perfectly where the edges match up and there are no gaps? For example, rectangles qualify, since you can make an area completely covered using them. Circles do not, since there will be gaps in between them as you can not match up all the edges.

Hi!!! I've tried this 7 times, and I keep getting 439 N as my answer, but I know that it is wrong... The book says that the answer is 929 N.

K, the overall question is that there are two forces, one being 600N and the other being 410N that form a 47 degree angle between them. Find the magnitude of the resultant and the angle that it forms with the larger force.

I can't really copy over my drawings, but I'm pretty sure that they're all right because I keep getting the same answer! Can someone PLEASE explain to me how to get the answer for this?? I know that the reason why I'm getting the ANGLE wrong is because I'm getting the magnitude wrong, so even if you can just help me with the magnitude, I can probably figure out the angle! :)

Thank you so much! I'll pick a best answer TODAY!
