A DC motor delivers mechanical power to a rotating stainless steel shaft (k = 15.1 W/m
Question:
A DC motor delivers mechanical power to a rotating stainless steel shaft (k = 15.1 W/m · K) with a length of 25 cm and a diameter of 25 mm. The DC motor is in a surrounding with ambient air temperature of 20°C and convection heat transfer coefficient of 25 W/m2 · K, and the base temperature of the motor shaft is 90°C. Using a uniform nodal spacing of 5 cm along the motor shaft, determine the finite difference equations and the nodal temperatures by solving those equations.

My name is Mubashir Farooq, and I have a Master’s degree in Information Technology. I am writing to express my interest for the position of tutor on SolutionInn.
My journey in the domain on Computer Science and Engineering started in 2011, when I got enrolled for B.Tech Computer Science and Engineering. Ever since my enrollment, I have been fascinated by the ever growing technologies and the need for new technology: I possess a great thirst for knowledge, learning new disciplines, and I am inspired by the subjects' complexity; as it gives me dedication and motivation to come up with innovative solution. I am particularly interested in Text Analytics. Every day, we create 2.5 quintillion bytes of data. This data comes from everywhere: sensors used to gather climate information, posts to social media sites, digital pictures and videos, purchase transaction records, and cell phone GPS signals to name a few. This data is so large and complex and find its applications across almost all sectors of our society and market. I am a man of an orderly character, and which inspires to aspire for neat and clear solutions. In my opinion every problem has a solution; it is just that we need to filter the solution space and construct ways of attaining a robust and clean solutions. I enjoy programming in C, C++, JAVA, and other programming languages. I have worked as IT Expert in MNC. Currently i am working as a tutor in my city. I have been in this job from last 2 years.
I have expertise in teaching from 4th grade till masters. My area is Computer Science for bachelors and masters students. Science and Mathematics from Grade 4 to Grade 12.
