it was about  circle the outer boundary is called circumference
the half the circle is diameter
and half of the diameter is radius

video# 2

in this video we watched how different size gears works .gear trains gear tooth 
12 teeth gear
24 teeth gear
36 teeth gear

video # 3
in this video a man was trying to unfix the bolt but he was unable beacause he was not that much forceful so he used an axis from the distance which created the moment this whole process called torque

half of the circle is called diameter and half of the diameter is called radius the outer boundary is called circumference

second video
in this video we watched gear trains different sizes of gears 12 teeth 24 teeth and 36 teeth gears

third video

in this video we watched the concept of torque how the gears moves with force and moment

d= 2 r
r= 1/2 d

video # 2

sizes of gears how they are responsible for the speed and direction

video # 3

in this video we watched the concept of torque force and axis

perimeter of a circle 
diameter and radius 


review of second video 

gears are of different sizes 
12 24 and 36 teeth gears 
gear trains how the speed changes 

video three review

gears moves with the concept of torque in which force is involved
