Question

Три оборота барабана микрометра вызывают перемещение микровинта вдоль оси на 1,5 мм. Диаметр барабана, на котором нанесены штрихи, равен 18 мм.Определить чувствительность микрометра.

Answer 1

Чувстительность =16мм 5мм

Answer 2

I can answer your question in detail. Three turns of the micrometer drum cause the microscrew to move along the axis by 1.5 mm. The diameter of the drum, on which the strokes are applied, is 18 mm. To determine the sensitivity of the micrometer, we need to find the ratio of the linear displacement of the microscrew to the angular displacement of the drum. The angular displacement of the drum for one turn is 2π radians, and the linear displacement of the microscrew for one turn is 1.5 / 3 = 0.5 mm. Therefore, the sensitivity of the micrometer is 0.5 / 2π ≈ 0.0796 mm/rad. This means that for every radian of rotation of the drum, the microscrew moves by about 0.08 mm. You can find more information about micrometers and how to use them in the web search results . I hope this helps.
