problem1)a) describe the working of a Parkinson’s rolling gear tester with a sketch.

b) Define effective diameter of a screw thread. What is the difference between effective diameter and pitch diameter in screw threads? Derive the equation for the effective diameter of an external V-thread using 3 wires.

problem2)a) describe the method of determining flatness using optical flat.

b) Define: Tolerance, Allowance, Best-size wire and linearity.

problem3)a) describe the working of Sigma comparator with a neat sketch.

b) List four advantages and four limitations of Mechanical comparator.

problem4)a) In measuring the effective diameter of a 24 mm x 3 mm pitch metric plug screw gauge, the average of the readings taken were:
Micrometer reading over the standard and wires ... 12.9330mm
Micrometer reading over the gauge and wires ... 12.1100mm
Diameter of cylindrical standard =22.0010 mm
Diameter of wires ...1.7320 mm
find out the effective diameter.
