I don't usually write comments, but I had to make it this time. Thank you for making the lessons easy to follow. During my class, I have trouble following along and would much rather have a professor like you. Anyone who has you as a professor is very lucky!

You have changed my life! I might actually pass statics because of you! You are so comforting and make things so simple. Thank you so much

I was so confused on 3D forces...until I watched your video. You're much better at teaching than my professor. Thank you so much

You might have addressed this in a later video, but it would be helpful to see the axes in a different orientation for a couple of problems. For instance, my text book has z coming "towards" us (where the x axes are in this video), so I'm having to figure out how to adapt the information in this video to apply to those problems. I did find this video very helpful, though, and I enjoy your teaching style (this guy's got jokes!)

I am so pleased I found this channel it's like discovering the mother lode of engineering mathematics and I want to say a big thank you for all your efforts. I seriously don't think I have ever encountered anyone so naturally gifted in the art of teaching as you. Simply outstanding.

You made everything so simple, I'm really grateful for this. I've been practicing the transverse triangles for hours and still I wasn't getting them right but you simplified everything into just identifying the angles and plugging in. Really helpful! Thanks!

I normally HATE statics and I dread it every single day this video actually made it fun and real interactive I wish all uni students were blessed with teachers like you

[bryanmuratalla]

You are the man!! I know that I should call you Dr Hanson or Professor Hanson, but I just want to call you brother, Dr. Brother, Professor Brother. Thank you for what you do!

[mattheywood]

You sir are a legend. Thank you for taking the time to make these videos!

[uguryigit]

just to let you guys know there is a small mistake in the playlist. The lesson 9 is put before the lesson 8.

For everyone confused... F1 is in the NEGATIVE Z plane so 90+30 = 120 degrees. You must look at it as the F1 is bellow the Y and X axis in the negative Z

i finally figure this one out... Thank you so much for providing a super clean path to calculate this through.😄

Dr Hanson, thank you so much for all your videos, I have watched many and have jumped around statics for a while. I am not a student, but enjoy the physical sciences and math.
I don't understand why for: F=100n, theta=50 deg, and phi=120 deg(why isn't phi = - 30 deg)
Isn't the lower half of the Z axis the negative area. Why can't the bottom half of the Z axis be negative..., since the X and Y axis are both neg. and posit. Thank you in advance

I miss the TTU logo on the side haha. is the statics series getting remade?

[Ghazali_tech]

I only missed 1st one that was great journey
Love from Pakistan

[johnsterling]

Seriously thank you! Wish I went to TT like a lot of my friends did lol!

DR. Hanson, I found the Practicing Blue Triangle Problems a bit confusing, however at the end I understand the concepts.

[roxanashahriari]

great video! I'm trying to do these in the workbook and I'm trying to write the Cartesian vector but i don't understand how to plug in the negative phi value

[nerdy]

Shouldn't Theta z be given positive or negative sign, depending upon direction of its rotation?

[a-dalematthews]

This video was great, made it super easy
