![]() Then find out the radius by dividing the value by 2. To do this measure the length and diameter of the cylinder as discussed previously. Once you have completed the initial measurements, use your skills to find the volume of a cylinder. Place the upper, smaller jaws in the cavity of the cylinder and open the jaws till their surfaces come in contact with the inner walls of the cylinder. To measure the inner diameter of a cylinder, slide open the moving scale of the caliper. Placing the cylinder parallel to the jaws can cause the cylinder to move off center resulting in an inaccurate measurement. To get an accurate reading make sure the axis of the cylinder is perpendicular to the jaws. To measure the outer diameter of a cylinder, hold the cylinder between the large jaws of the caliper firmly. ![]() When the object is in place take the reading from the scale as discussed previously. To measure length hold the object firmly between the calipers jaws from end to end. Disengage the locking screw and then check movement again. If the movement seems restricted check if the locking screw is engaged. ![]() ![]() Measure the Length of an Objectīefore starting the measurement slide the moving scale using your thumb to check if it is moving freely. Here are a few exercises for students to carry out: 1.
