this lecture series is great but mr anubhav agrawal please also make a comprehensive lecture series on industrial engineering,theory of machines and fatigue loading

as you can see i joined 4 days ago only...and each lessom takes about 1 hour of preparation...so it is very difficult to make series on such long subjects quickly...... in som we are having about 10 modules still remaining... but i will definitely cover fatigue loading for som perspective.... more info about fatigue will be on design.. if you are not understanding a particular topic I can make a video series for that... or you can contact me personally

since i am studying at my own i find balancing to be quite time consuming , and industrial engineering as well from som please make a video on pressure vessel

okay bro i will make video on balancing separately for you... and i have to decide whether to start principal stress or pressure vessels next

  1. ENGINEERING STRESS Definition- Internal resistance force per unit area acting in a particular plane Arsta sbuss


  2. Stress is tensor i.e. it depends on magnitude, direction and a plane. 6 1 Stress is not a measurable quantity. . Units . SI-N/m2-Pascal (Pa) (Stress value is generally of high magnitude so we don't use SI unit) Derived unit: KPa (103 Pa) Mpa(106 Pa -> mostly used) Gpa (109 Pa)


  3. Stress is independent of material properties. Getting bored lets apply what we learned GATE 2013( 1 marks) A rod of length L having uniform cross-sectional area A is subjected to a tensile force P as shown in the figure below. If the Young's modulus of the material varies linearly from E to E, along the length of the rod, the normal stress developed at the section-SS is Q.10 EI L/2 BPEE) PE (C)2 PE AE (D)
