Exactly. My current teacher (in a related course that uses all this stuff but higher level) is pretty nice, but the stuff is just tough. And this stuff... I can sit there for 6 hours not knowing something going across all sorts of resources, then sit here and in 5 minutes learn a crap ton on these videos. I started watching this channel almost 2 years ago and am still dumbfounded by how well it works.

Dr. Hanson, thank you for TEACHING us your ways. I would be so lost without this channel.

Learning statics is literally the only reason why I went to university, and here I am back to watching KZbin videos to learn its anyway! Subbed. This is so much more useful than mindlessly memorizing trigonometric identities and functions just so you can write a series of equations to prove that the sky is blue.

@abhijitsinghrait Жыл бұрын
Had the same query. Likely because its a symmetric truss and we have the roller on one side (where reaction would only by along y-axis), and there are no external forces in x direction. Therefore on the pinned connection, the reaction along the x-direction would be zero.
@ambrose_84 жыл бұрын
Can anyone confirm this alternative way of solving for KD and KJ: @12:20, we could instead rotate the axis so that x and y align with KD on the y-axis and KJ on the x-axis, and then solve from that?

I think typically we can't do that cause KD and KJ aren’t perpendicular

Why at the end you did not count the force in the Y direction going down that is equal to 20 KN and will make JD be 13.3 KN? Please let me know if it was just a little mistake or I am missing something.
@robertrobayo57443 жыл бұрын
Idk if you still need this but if we do the FBD at joint D and do the sum of the forces in the y direction it would be [DJ - 20 - 7.46sin63.4 - 7.46sin63.4 = 0] Therefore DJ = 33.341 It looks like you forgot to add the 20KN force

I don't know if you are still answering questions on here or not. But... I see you have 2 different supports, a hinge and a roller. The hinge has 2 reactions (x,y) and the roller only has 1 (y). So I assume the support is irrelevant?

@ralphbarbato54474 жыл бұрын
Compression is when the force is acting towards the joint; He assumed the member to be in compression so it ended up being a positive value. Typically when you don't know which direction the force should go, you can assume Tension and then any negative values would indicate that the member is in compression.
