u r given a thread and a meter scale. how will u estimate the diameter of the thread?
For measurement of any circular body most accurately we use screw gauge and it is not possible to calculate the dimeter or radius of the thread by using the meter scale , but from meter scale we can measure the length of thread.
hence it is not possible to measure the diameter of thread by using the meter scale.
