NCARB's Practice Tests  Earlier Versions
Is anyone aware of a forum or website, or any resource that offers a detail review of Version 3.1 of NCARB's Practice tests?
I have seen a few of questions that seems relevant to PDD, some of which I could not understand how they arrived at the answer. Here is one, if any one can help, i would appreciate it.
Lateral Forces ARE Study Guide: Multiple Choice Version 3.1 (Page 39, Question 4)
4. The diagram below shows an exterior exit door, 3' 0" x 7' 0" [910 x 2100],
subject to a net positive wind pressure of 20 psf [1.0 kN/m2, unfactored].
What force must be exerted at the center of the door to open it?
F 210 lb [0.95 kN]
F 420 lb [1.9 kN]
F 630 lb [2.9 kN]
F 840 lb [3.8 kN]
When I did this, i got 630ibs using the formula F=M/S. But the correct answer is 420!!!

Hello Bankole,
Unfortunately I'm not aware of any resource for earlier versions of NCARB Practice tests, but Ido have a thought on the sample question posted here.
It sounds like the question is asking for what force on the door would be equal and opposite to the force from the wind pressure.
Taking the area of the door (3' x 7' = 21 sf) and multiplying by 20 psf from the wind gives you 420 pounds of force.
Hope that helps!

I wouldn't use older exams. The topics just don't align now.
Hope this helps!

No need to spend too much time on structural calcs. Just focus on understanding the concepts.
