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. Least count of given screw gauge is

A student measured the diameter of a wire using a screw gauge with least count 0.001cm and listed the measurement. The correct measurement is

In a screw guage the graduation in the circular scale consists of 100 equal divisions and 10 complete rotation of athe cap is equivalent to 5mm on the main scale . While measuring diameter of a wire with screw gauge a particular observation gives initial circular cap reading as 57 and after completing 3 complete rotation the final circular cap reading as 63 . it is observed that while proceeding from initial reading to final reading the cap reading increases. calculate the diameter of the wire from the above data.

The density of a solid ball is to be determined in an experiment. The diameter of the ball is measured with a screw gauge, whose pitch is 0.5mm and there are 50 divisions on the circular scale. The reading on the main scale is 2.5mm and that on circular scale is 20 divisions. if the measured mass of the ball has a relative error of 2% , the relative percentage error in the density is
