  How to draw Vector Diagram for Motion of Simple Pendulum as a Simple Harmonic Motion ? - Smarter Techniques     Simple pendulum is a heavy particle tied at free end of   long   suspended   string at support. But in practice instead of heavy particle heavy bob is attached.   The length of pendulum is the distance between point of support and center of bob.   The bob oscillates and performs   Simple Harmonic Motion ( S.H.M. ). Fig A represents oscillating simple pendulum. Fig A     Consider bob of mass m is attached to string of length L and is oscillating between A and C. Let the pendulum be at an angle Ө from vertical.      The weight mg   is    resolved into two components mgcos Ө as ǁ component   and mgsin Ө as ⏊ componen t. mgcos Ө is balanced by   tension in sting   and mgsin Ө acts   as restoring force to bring bob to   mean ...

  How to Draw Vector Diagram for Vehicle moving on   curved Banked Road ? -  Smarter Techniques     Banking means making road bed slightly inclined to horizontal . This is done   at curved road for safe driving . Fig A represents cross section of banked road along with vehicle on curved road.      Fig A Consider vehicle of mass m moving with velocity v on curved road of radius r and banked at angle of   Ө .   Normal reaction N is resolved into Nsin Ө and Ncos Ө .   Nsin Ө acts as   centripetal force   mv 2 / r   on   vehicle.                 ∴   Nsin Ө = mv 2 / r   and   Ncos Ө = mg   = Weight of vehicle. Using these equations we get    This is the safe velocity of vehicle on banked curved   road. In my blog related to   How to Draw Diagrams in P...

  How to Draw Diagrams in Physics  by using   Smarter Techniques ?         Physics is one of the important subjects particularly for std X to XII students. There are different easier methods to study Physics, such as  Experimentation, Relating the topic to everyday life examples and so on. With my 40+ years experience in  Physics teaching, I have developed Smarter methods  of drawing diagrams so as to make Physics study meaningful.       Usually teachers explain diagrams by drawing them on black board. Students draw diagram by learning also from books, ppt , Google Image, etc. But in all these cases there is no information regarding how to draw diagrams actually  on answer sheets of A4 size.        Do you want know the technique? So let’s learn the smart techniques  of drawing diagrams on A4 size answer sheet.   If the diagrams are drawn with the help ...
