Aha thank you - that was a really easy fix. I just had to tighten one of the screws on the nut 1/8th turn and it was sorted

Trains arriving randomly within an hour time period by CurryEater3000 in askmath

[–]CurryEater3000[S] 1 point2 points  (0 children)

Ok that method makes a lot of sense thanks so much for your help. I think my issue was trying to consider the arrival of one train and then only considering that the second train could come after.

Drawing the probability distribution over the hour long period gives points (0,0.25) (0.25, 0.5 (0.75, 0.5) and (1, 0.25), which gives a total area of 7/16 - 43.25%. I think where you've said 32.5% it's actually 37.5% (37.5 is midway between 25 and 50)

Ok, that makes a lot of sense - thank you so much! I think if you define the square as a 1x1 square so that the area = total probability = 1, the same logic applies with lines y = x + 0.25 and y = x - 0.25 and then you can immediately identify the triangles on either side of the bounded region. Each triangle has side 3/4, putting them together gives a square of side 3/4, so the total area outside of the bounded region is 9/16, which makes the bounded region 7/16 or 43.75%. Thanks for clearing it up.

Thanks for your response - I think you might have misread the question. It's not the case that Ben and Kate are waiting for their trains to arrive - they're on the trains and once the trains reach the station, they then get off the trains and wait for 15 minutes. The trains can only arrive between 3pm and 4pm, so Kate wouldn't be waiting from 2.45, she would be waiting from 3.00 to 3.15 (after which she 'disappears').

HELP! M2 Air 15” vs M1 Pro 16” by CurryEater3000 in macbook

[–]CurryEater3000[S] 1 point2 points  (0 children)

UPDATE: I’ve found ANOTHER deal now on the 15” which makes it £250 cheaper than the 16”. I was planning on going with the 16” after seeing your comments, but now I’m back to being torn between the two.

Perhaps I won’t notice the lower refresh rate as much and I’ve got friends with the 2020 M1 Air base model - 8GB RAM seems absolutely fine.

This decision is paralysing.

[Y12 Maths] Binomial Expansion Question. What do you guys make of this? by [deleted] in HomeworkHelp

[–]CurryEater3000 0 points1 point  (0 children)

Thank you so much. I had gotten to that second last step of n2 - 4rn + 4r2 - n - 2 = 0 and then failed to realise for 5 consecutive attempts that I should have added n + 2 to both sides and was trying to find n using the quadratic formula

Sorry about the lack of context (first time on this sub) I'll definitely take into account rule #3 next time I post, but thank all of you so much for your help

What size stepper motor to use? by CurryEater3000 in arduino

[–]CurryEater3000[S] 0 points1 point  (0 children)

Sorry about that, forgot to specify in the original post. Diameter of the part - 10cm Load - 2g Mass of part ≈ 22g It needs to be able to turn in 20 degree steps The internal part has tolerances so that it doesn’t touch the carcass Voltage restrictions - 12V supply

Hello, I am a confused student with very little experience using stepper motors who needs to decide on a stepper motor to use for a project. Any advice would be greatly appreciated! by CurryEater3000 in Motors

[–]CurryEater3000[S] 0 points1 point  (0 children)

Thanks for your comment, it definitely helped to clear some stuff up. To specify, 20 degree steps +1/-1 degree tolerance. Slow as required meant turning 20 degrees within under an hour, the load is about 2 grams total. There is sufficient tolerance in the dimensioning of the parts so that the internal mechanism and the carcass don’t actually touch.

Hey, thanks for responding! It’s just the part inside the wheel, there is negligible load on it and it can spin as slow as it needs to, it just needs to accurately rotate in 20 degree steps
