Good Morning,

One quick question. I was curious on your fiFiLi for member FG. It might just be that I haven’t had my coffee yet, but when I multiply the components 3sqrt(2)*50sqrt(2)*sqrt(2) I get around 420. Not quite sure if it’s a typo in the lecture or I’m missing something.

Thanks!

Hey @Jonathan_Snow - it was me who hadn’t had my coffee!! You are correct, it works out to be 424. When you follow this correction through the deflection ends up being 1mm rather than 1.5mm.

Thanks for flagging this…this comments will surely save someone else from the same confusion :grinning_face:

Best,
Seán
