how do u guys draw the lens.. using compass or stencil?

the gear ratio is greater than one for gain in torque right??

Can anyone pls tell me that y do v have to use 1000 in Question 8.b. (ICSE Physics specimen paper).2017

Can free vibrations be practically obtained??

What are u guys using for drawing pulleys??procircle or rounder (don't use coins please it is not allowed)
