I was just playing with some numbers and I noticed this weird pattern. Because of the complexity of the problem I am finding it hard to describe it in words. But you can easily understand it by looking at the picture. Whenever I form a series by adding numbers in Arithmetic progression to the...
Hello all,
This one thought came to my mind just now. What's the physical significance of signal representation in negative time, i mean second and third quadrant.
So for example, sin(t) and sin(t).u(t) aren't they same for all practical purposes?
I know, mathematically they are...
Do non periodic signals have frequency? Because my pretty general rule
f = 1/T
says that they have zero frequency.
But suppose i analyze a voice signal. We generally associate a term frequency with them. If you ever had used audacity you might have noticed that the graph is quite...
I am trying to master "AT89C51 datasheet" by understanding it completely. But my limited knowledge is hindering me. help me to overcome all obstacles.
It says that Port 0 is an open-drain port. Does it mean that it can only sink current and can't source current? On the next line it says that...
Hi all,
I remember my school days when i used to be a very excellent student of my class. I got admission in an engineering institute. I moved to other city for my studies. I rented a room to live in that strange new crowded city. No mom there. I've always been a mamma's boy.
With the help...

Hi,
I am a 4th semester engineering student of electronics and communication discipline. My semester is going to end and I am very worried about the vocational training. I am from a small town and I don't belong to a very rich family. Should i collect money and move to a big town like New...
Not working
My latex code is
\begin{flalign*}
E_1 & = \frac{e_{1max}}{\sqrt{2}}\\
& = \frac{N_1.{\phi}_m.w}{\sqrt{2}}\\
& = \frac{N_1{\phi}_m.2\pi.f}{\sqrt{2}}\\
\\
E_1 & = 4.44 N_1.{\phi}_m.f\\
\\
E_1 & = 4.44 N_1.B_m.A.f
\end{flalign*}
and after using \boxed in E_1 & = 4.44...
sorry it was sine not cosine. so p will be minimum for max value of sine. i.e theta minus phi is equal to ninety. thanks tiny tim you really explained me in a very interesting nice and smart way.
i am on phone so I'm inclined to use texting language. please ignore if you feel that my posts are...
Sorry, I made a mistake here.
Here's the correct one
For body B
N = 150 cos 60 = 75 N
T =\mu N + 150 sin 60
= 145 N
For body A
R + P sin\theta = 100 ......(i)
\mu R + 145 = P cos\theta
= 0.2 R - P cos\theta = -145 ...(ii)
