To Measure The Thickness Of The Given Sheet Using Screw Gauge - Practice Questions & MCQ

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 sheet. If the main scale reading is 2 mm and the thimble scale reading is 25, what is the thickness of the sheet in mm?

A screw gauge with a pitch of   and a circular scale with 50 divisions is used to measure the thickness of a thin sheet of Aluminium. Before starting the measurement, it is found that when the two jaws of the screw gauge are brought in contact, the   division coincides with the main scale line and that the zero of the main scale is barely visible. What is the thickness of the sheet if the main scale reading is and the  division coincides with the main scale line?

An experiment is conducted to measure the thickness of a thin sheet using a screw gauge. The main scale reading is 2 mm, and the circular scale reading is 25. The pitch of the screw gauge is 0.5 mm, and the least count of the instrument is 0.01 mm. Determine the thickness of the thin sheet.

A screw gauge is commonly used to measure the thickness or diameter of a thin sheet or wire. In an experiment, a thin wire is measured using a screw gauge. The main scale reading is 3 mm, and the 10 divisions on the circular scale coincide with one main scale division. The pitch of the screw gauge is 0.5 mm, and the zero error is −0.02 mm (i.e., the zero of the circular scale is 0.02 mm below the reference line). Calculate the diameter of the wire.

A laboratory experiment involves measuring the thickness of a thin glass sheet using a screw gauge. The main scale reading is 2.5 mm, and the circular scale is divided into 50 divisions. The screw gauge has a pitch of 0.5 mm, and there is a positive zero error of 0.04 mm.

Calculate the actual thickness of the glass sheet.

A laboratory experiment involves measuring the thickness of a thin plastic sheet using a screw gauge. The main scale reading is 1.5 mm, and the circular scale is divided into 50 divisions. The pitch of the screw gauge (p) is 0.2 mm. The screw gauge has a negative zero error of −0.01 mm.

Calculate the actual thickness of the plastic sheet.

A precision laboratory experiment requires measuring the thickness of a very thin film using a screw gauge. The main scale reading is 0.8 mm, and the circular scale is divided into 100 divisions. The pitch of the screw gauge (p) is 0.125 mm. The screw gauge has a negative zero error of −0.03 mm.

Calculate the actual thickness of the thin film.

A precision experiment requires the measurement of the diameter of a small spherical object using a screw gauge. The main scale reading is 4 mm, and the circular scale reading is 34. The pitch of the screw gauge is 0.2 mm, and the least count of the instrument is 0.005 mm. The object is placed between the screw and the anvil, and the screw is turned until it just touches the object. Determine the diameter of the spherical object.

A laboratory technician needs to measure the thickness of a very thin metal plate using a screw gauge. The main scale reading is , and the circular scale reading is . The pitch of the screw gauge is , and the least count of the instrument is . Due to the delicate nature of the plate, it is important to apply very gentle pressure while measuring its thickness. Determine the thickness of the metal plate.
