False. As the pitch of a single start screw of a standard metric micrometer is 0.5 mm and the barrel division are 0.5 mm apart, one revolution of thimble will move a distance of one barrel division. The purpose of ratchet screw in micrometer screw gauge is (a) to lock a dimension (b) to impart blow motion (c) to maintain sufficient and uniform measuring pressure (d) to take care of wear of screw threads (e) to allow zero adjustment. B. Sindh MCQs, 10th Class MCQs, Physics MCQs, Measurment MCQs, 1mm , 0.1mm , 0.001mm , 0.01mm 1.16 cm. C. 1.26 cm. 45. Which graph shows how the speed of the ball changes with time? What reading was recorded? State one advantage and one disadvantage of using the micrometer screw gauge for measuring length. 1.06 cm. 9. View Answer. The precision of a micrometer screw gauge is 0.001 cm. A the area of a sheet of paper C the thickness of a sheet of paper B the mass of a sheet of paper D the volume of a sheet of paper MAR 19/P22/Q1Which row shows the best choice of measuring instruments to obtain accurate values for the distances shown? 1 The diagram shows part of a micrometer screw gauge. Page 6 of 32 Solution advantage: high accuracy, accurate to 0.01mm disadvantage: has a short range usually between 0 to 25mm 8. www.gtu-mcq.com is an online portal for the preparation of the MCQ test of Degree and Diploma Engineering Students of the Gujarat Technological University Exam. A 0.0001 mm B 0.01 mm C 0.1 mm D 1 mm 2 A small, light ball is dropped from the top of a tall building. Which quantity can be measured directly using a micrometer screw gauge? The diagram shows an enlargement of the caliper scales. 0 mm 12 45 40 35 30 What is the smallest reading that can be achieved using this micrometer screw gauge? A screw gauge with a pitch of 0.5 mm and a circular scale with 50 divisions is used to measure the thickness of a thin sheet of Aluminium. Discuss in Forum . A quick guide on how to read a micrometer screw gauge.Similar to the way a vernier caliper is read, a micrometer reading contains two parts:. A. Before starting the measurement , it is found that when the two jaws of the screw gauge are brought in contact, the 45th division coincides with the main scale line and that the zero of the main scale is barely visible. A student used a vernier caliper to measure the length of a small wooden block. ... What is the purpose of using a ratchet screw in the micrometer screw gauge? the first part is contributed by the main scale on the sleeve; the second part is contributed by the rotating vernier scale on the thimble True. Measurement of Screw Thread and Gear; 4. A. 10. B. Discuss. 7. Solution. The screw has a lead of 0.5 mm and the thimble and barrel are graduated as shown in the figure below. The purpose of adjusting nut in a micrometer screw gauge is to (a) take care of zero error The purpose of ratchet screw in micrometer screw gauge is A.To lock a dimension B.To impart blow motion C.To maintain sufficient and uniform measuring pressure D.To take care of wear of screw threads . Basically it is a screw with an accurately constant pitch (the amount by which the thimble moves forward or backward for one complete revolution). can be very long Question 1. 46. D. 1.36 cm. State 4 advantages of using the measuring tape as an instrument for measuring lengths. The micrometer screw gauge also uses an auxiliary scale (measuring hundredths of a millimetre) which is marked on a rotary thimble. the least count of a micrometer screw gauge is:?
