Screw gauge is said to have a negative error.

Explain the principle of a screw gauge and explain the method of determining the diameter of a wire .

Least count of screw gauge is defined as.

if 17 divisions of the circular scale of a screw gauge are below the index line of the pitch scale then the zero error is "_______" circular divisions.

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

A screw gauge has a positive error of 4 division .When this screw gauge hold's sphere the main scale reading is 4 mm and the head scale coincinding division is 24 . If its least count is 0.01 mm find out he the volume of the sphere.

The radius of a ball bearing measured by a screw gauge is 3.75mm . The pitch of the screw is 1mm and it has 100 divisions on its head scale. The percentage error in the volume of the ball bearing which is perfectly spherical by shape is
