Calculating the total resistance in an electrical circuit, lol. I studied it, but it never came up on the test.

Most of that seems pretty easy to me. I saw a bunch of other questions from other pages of this thread that threw me off. Some very obscure one-off questions about temperature/nuclear reactors/etc. The last two you mention about velocity and piston exerting force, where would I find an example of these questions? Didn't know them so trying to make sure I do.
I can't guarantee you won't see the one-off questions. Maybe I just got lucky? Who knows. My OAR was a 56, which is above average, but nothing jaw-dropping. I assume the tough questions come out if you're doing well.
I think the piston question I had was even easier than I stated above. Something like "at what position would the piston be open/closed (or whatever terminology is actually used for pistons)" or something super easy like that. No calculation or anything, but I remember it asking about position. Maybe the Barron's book has some? I didn't study it at all, and I don't think there's really a need to IMO.
The velocity questions also don't really require practice necessarily. Just know that if two objects both start with a vertical velocity of zero, they'll hit the ground at the same time. I probably had 3 questions on this. If you watch Mythbusters, they did this experiment by shooting a bullet out of a gun, and dropping a bullet right next to the gun. They hit the ground at the same time. One of the questions was something like "Person A throws a rock sideways off a cliff and Person B drops a rock off the cliff at the same time, whose rock will hit the ground first?" A, B, or same time?
I know this didn't really give you examples of practice problems, but you won't need them if your questions are like the ones I had.

Algebra is always the hardest part of any math or physics problem. Thank you!

it is just 1:1, correct me if I am wrong but each of the gears has 7 points so they all are turning similiar

How do you get that though? I think I'm confusing myself. I see that all the gears have the same teeth, but if they all had different # of teeth, how would you break it down?
MA = # teeth on output gear / # teeth on input gear

DC: current flows continuously in the same direction
AC: the current changes direction periodically
What is the advantage of AC?
AC: the current changes direction periodically
What is the advantage of AC?
If you google "advantage of ac over dc" the first link provides a nice summary.
I think you're correct in your calculation of the box weight too.

Been browsing this website for a long time and finally took the test. Sucked because I drove an hour and a half to start and it crashed halfway through but went back yesterday and completed it. Ended up with a 52 7/8/8. Majored in Criminal Justice with a 3.89 GPA from a private university and hoping for SNA. What kinds of recommendations do you all think would work best to be competitive? I have recommendations from a former captain in the AF, a former navy corpsmen/current police officer, and two former professors. Wasn't sure how well those would work. Also, what kinds of PT scores will be best?

So I took the ASTB yesterday! Boy did it make me feel stupid. I definitely was going in trying to get above a 60 and ended up with a 54. Really upset about this but I'm gonna keep it.
By far, reading was the easiest section. It really is just narrowing it down to two choices, after that it's just rereading and making sure the verbiage matches the paragraph. The sample questions posted on the Navy website had some that were verbatim in the exam. That is the best example of the type of questions.
The math section really made me feel stupid. I remember some of the questions well. First one was like, probability of two Chicago teams winning is .15. If the probability of one of them winning is .40, what is the probability of the other. I got one that was like, in the infinite series of 1/n + 1/2n + 1/3n......+L = 1, what is N? I got one asking for the sum total if you add 2+3+4+5+6.....all the way until +123. No logs. One about minimum function on a graph or something. Huge equations to simplify and answer. like (-2)-[-3(4)-(6{3*5}3) + 6. One about right triangle integers, gave you the area, asked for perimeter. One where you plug in a number into N for an equation. Lots of simplifying square roots or adding/subtracting them. One of those problems about a certain amount of coins, like, if there were 20 quarters and the total is $50 how many dimes are there (not accurate numbers just example). If you flip a coin three times what's the probability of you getting tails. What is the 6th term in the series, where it was like 10, 18, 26, etc. Just adding eight every time. Man is paddling at 4 km across a river when the river is flowing 5 km down, how fast was the boat? D=RT questions about two people leaving at different times at a certain speed and a what time were they 400 miles apart (5 hours). One question about a car driving in three legs of a trip, first leg 60 mph for 40 mins, second leg 30 mph for 20, and third leg went at the average of the first hour of the trip. Question about something being discounted a number of times and taxed. Which fraction is the smallest, and then it gave like 31/32, 10/11, 2/3, and something else. Susan took four tests, each test was 10 points higher than the previous test. She got a 70, 75, and 80 on first three tests. She got a final grade in the class of 75. What did she get on the 4th test?
By the time I got to mechanical I really was burnt out and don't remember much. A lot of fulcrum questions where you have like 40 * 3 =10 * X. Equation for work, equation for power, V=IR one. One about bernoulli principle. One about mechanical advantage and pulleys. One about torque and which angle of pushing a wrench down is the best. One about if a screw was stuck, which point would you use a blowtorch on to get it off. If a coil was wrapped around a nail with a 1.25 amp charge, and you removed the nail and straightened the coil it was .25 now, what was the charge on the nail or something like that. If a compressed string rests at Point A and expands to point C before coming back, when does it have the greatest energy? Ice cubes floating in water are an example of how when water freezes it (decreases in weight, increases in density, expands in volume). Had one about angular velocity of a man on a unicycle. Lift on airfoil.
All of my tests went on until the max time limit. I really want to thank everyone on this forum recently and throughout the years for contributing their experience/study guides/thoughts. Submitting for May SWO board.
