What is zero, positive and negative error in a screw gauge? Physics practical
A screw gauge is a precision instrument used to measure very small thicknesses or diameters with great accuracy.However, like any measuring instrument, it can have errors.One common type orf error is called zero error, which occurs when the zero mark on the circular scale of the screw gauge does not coincide with the zero mark…
