The moment of inertia is a measure of an object’s resistance to changes in its rotation. It must be very specific to the chosen axis of rotation. Also‚ it is specific to the mass and shape of the object‚ including the way that is mass is distributed in the object. Moment of inertia is usually quantified in kgm2. An object’s where the mass is concentrated very close to the center of axis of rotation will be easier to spin than an object of identical mass with the mass concentrated far from the axis

Lab 1 – Measurement of Space and Time Anthony Lucci Lab Partner: Amy Hayes Question 4: Both the height and diameter of the cylinder were taken to find the volume; five times for both measurements. Vernier calipers were used to get these measurements by clamping the cylinder between the jaws of the calipers. By looking at the mark of the zero‚ in relation to the main scale‚ the line best lined up with a line from the main scale was taken down. Getting

Measurement of the distance‚ the thickness and the radius of curvature Purpose : To learn how to use vernier caliper‚ micrometer and spherometer to measure internal and external diameters of a pipe‚the thickness of a copper rods‚ and the radius of curvature of spherical lenses. 1) Vernier caliper: As shown in Fig. 1 the main fixed scale in the vernier caliper has 1 mm gradations while th sliding scale (vernier scale) has 0.05 mm gradations. The smallest division of vernier scale is called
