When you are finding the image. Try this instead- 1. Define the line line equation - that is, z0 - u = λv (u, v are the vectors you mentioned) 2. Consider a point z0 on the line you defined. 3. Find the position vector of z wrt this z0 That is z - z0 4. Find the foot of perpendicular of z on...

I don't know why it got blurred. Actually I resolved the problem. y'Δy is nothing but mitiplying the transpose of vector components of y with the symmetric matrix Δ = L'1AL1 L is the 1x3 matrix of eigen values of a symmetric matrix A. And then multiplying the result with y vector. This gives the...

When you say z' = x' + iy', is the z' supposed to be the image of the point z wrt the mirror line passing through u in the direction of v?

Hello everyone, I actually had a problem with understanding the part where they have defined L'AL = Λ. There, they have taken γΛγ1 = Σy2λ = 1. Why have they taken that? Is it arbitary or does it come as a result of a derivation? Thank you

Hello, I tried looking this up a lot and just could not find it. For four bar linkage, Klein's construction is used to find velocity and acceleration of piston and connecting rod. Here is a link for the procedure of the same...

Hello to everyone, I am an undergrad mechanical engineering student. Currently in 4 semester. I have this one major problem. I cannot memorize facts and diagrams. We have this subject, production technology, which consists of lots and lots of facts and for me an overwhelming amount of...

I found ocw - Precision Mechanical Design from MIT which asks me to start with the ocw on Mechanical Design. I have the book for Mechanical Engineering Design by Shingley. So, your take is I learn Mechanical Design and then move on to PMD?

FIrst, apologies for posting in the wrong forum. I would like to start with learning completely how basic measurement systems like strain gauges, etc work and then slowly move to optical measuring instruemtns and finally top lebel CMMs, etc/

Hello, I have metrology in my 4 semester in Bachelor's of Engineering in Mechanical Engineering. However, the books that we get (Engineering Metrology, R.K Jain,) give only a brief principle of how the instruments work. I want to further my study of this subject with an intention to design...

Sirs, Thank you for the answers. I think I have understood. However, I would like to articulate my understanding. So, as jack said, for every movement of say one link, the other links if they move in only one way and end up in only one position, the two links are counted as moving together in...

Hello guys, I have a doubt with understanding DOFs. I have taken the example of the four bar linkage. According to Grueblr's condition, the DOF of this mechanism is 1. \mbox{DOF} = 3(l-1) + 2j_1 + 2j_2\\l=4\ j_1=4\ j_2=0\\\mbox{DOF} = 1 In the above figure, the links next to the ground link...

Looking forward to learning a lot in the 2 and a half years I have. However,. I keep getting stuck here and there. Mainly because I didn't perfect my basics of physics[emoji17]

Hello guys, I am a 2 year B.E student in mechanical engineering. I like solving mechanics of materials, math parts veru well( excerpt numerical methods). Reading and YouTube ate my favourite hobbies. Nice to meet you
