Measurement and Errors
While measuring the diameter of a wire by screw gauge, three readings were taken are $$1.002$$ cm, $$1.004$$ cm and $$1.006$$ cm. The absolute error in the third reading is?
What is the cause of backlash error?
Due to continuous use or due to its wear and tear while the screw is moved by rotating screw head, it slips in the nut and does not cover any linear distance for some rotation of screw head. This is the cause of backlash error.
