the no. of circular division on the shown screw gauge is 100 . it moves 0.1 mm on main scale for complete rotation and main scale has 1 mm marks. the diameter of the ball is.
Answers
The diameter of the ball is 0.001 mm.
Calculating the diameter of the ball:
To determine the diameter of the ball use the following formula:
Diameter = (Pitch of the screw / No of circular divisions) x No of rotations
From the data
Number of circular divisions on the screw gauge = 100
Screw gauge moves 0.1 mm on the main scale for a complete rotation
Main scale has 1 mm marks
First, let's calculate the pitch of the screw gauge.
The pitch is the distance moved by the screw for one complete rotation. Since the screw gauge moves 0.1 mm on the main scale for a complete rotation, the pitch is 0.1 mm.
Now, let's calculate the number of rotations. One rotation of the screw corresponds to 1 mm on the main scale. Since the main scale has 1 mm marks, one complete rotation would be equal to 1 mm.
Using the formula
Diameter = (0.1 mm / 100) x 1
Diameter = 0.001 mm
Therefore,
The diameter of the ball is 0.001 mm.
