Screw Gauge

Assuming negligible zero error, Find the thickness of the wire,If In a screw gauge, 5 complete rotations of the screw cause if to move a linear distance of 0.25 cm . There are 100 circular scale divisions. The thickness of a wire measured by this screw gauge gives a reading of 4 main scale divisions and 30 circular scale divisions.

The pitch of a screw gauge is 1mm and its cap is divided into 100 divisions. When this screw gauge is used to measure the diameter of a wire, then main scale reading is 2 mm and 58^(th) division of circular scale coincides with the main scale. There is no zero error in the screw gage. Then the diameter of the wire is

The meehanism behind nut and bolt arrangement also works for screw gauge. In case of nut and bolt mechanism, with rotation of bolt, it has translational movement also. In one complete rotation of bolt, tip of bolt moves by a linear distance equal to linear distance between two consecutive threads on the screw, known as pitch in case of screw gauge, the circular scale is divided in several parths. The ratio of pitch and total number of divisions on circular scale is known as least count. Spherometer is a device used to measure very small distances such as radius of curvature and thicness of thin plate. The screw gauge can be used to meaure diameter of a spherical sample. A screw gauge has 100 divisions on head scale and in 8 rotations distance covered is 8 mm. A screw gauge has which of the following characteristics ?

The pitch of a screw gauge is 1 mm and there are 100 divisions on the circular head. While measuring the diameter of a wire, the main scale reads 3 mm and the 55th division is in line with the base line. Find the diameter of the wire. Assume that the screw gauge is free from zero error.

Fig. below shows the reading obtained while measuring the diameter of a wire with a screw gauge. The screw advances by 1 division on main scale when circular head is rotated once. Find the diameter of the wire.

The pitch of a screw gauge is 0.5m and there are 50 divisins on its circular scale and one man scale division =0.5mm . Before starting the measurement, it is found that when jaws of the screw gauge are brought in contact, the zero of the circular scale lies 5 divisions above the reference line. When a metallic wire is placed betwen the jaws, four main scale divisions are clearly visible and 16^(th) division on the circular scale coincides with the reference line. The diameter of the wire is

Two full turns of the circular scale of a screw gauge cover a distance of 1mm on its main scale. The total number of divisions on the circular scale is 50 . Further, it is found that the screw gauge has a zero error of - 0.03mm . While main scale reading of 3mm and the number of circular scale divisions in line with the main scale as 35 . the dimeter of the wire is

The pitch of a screw gauge having 50 divisions on its circular scale is 1 mm When the two jaws of the screw gauge are in contact with each other, the zero of the circular scale lies 6 divisions below the line of gradution. when a wire is placed between the jaws, 3 linear scale divisions are clearly visible while 31 division on the circular scale coincides with the reference line. Find diameter of the wire.
