do u have the original question

I can recall from memory, but I don't have a copy of the question. Mass of boat was 1.2ton, incline angle was 30, winch angle was 40 from horizontal at the top and coeff of friction was 0.4

what was ur working

Also graphical method for completeness.

 

[Shabloinker]

yeah thats right i got that aswell

did you guys remember getting% 62 point something percent efficiency?

I think so, should've since we got same force

what did u guys put for signal strength testing

I wrote something about cable attenuation testing idk if thats right though

alot of kids put megohmeter in my class. I think it was an antenna, cause it measures signals in dB.

what about the rectification one

 

[splatcat]

what about the rectification one

half wave and full wave for the types. Wave drawings are easy, single diode only put the positive values and exact same and for no cap you just flip the negative and for the one with caps it is kind of level but bonces. Cap smooths it out for final bit

Megohmmeter is for insulation testing, not signal strength?

 

[splatcat]

also it said describe a method, does that mean we had to name a tool?

yeh idk. signal strength was a very niche testing method but I had a rlly small bit of it in my notes.

I think so. It was a device that can be used to measure it

might be cooked for that question, just mentioned measuring signal power at each end to find attenuation

what do u reckon scaling will be like this yr? Similar to last yr?

raw marks database barely has anything for this subject. Probably similar scaling

Scaling tends to be prtty good for engo, like an 88 goes to a 93.
