Procedure:1. Measure the dimension of the cylinder. Determine the diameter of the specimen to the nearest 0.01 in (0.25 mm) by averaging three diameters measured near the ends and the middle of the specimen and lying in the plane containing the lines marked on the two ends.2. Determine the length of the specimen to the nearest 0.1 inch (2.5 mm) by averaging at least two length measurements taken in the plane containing the lines marked on the two ends.3. Center one of the plywood strips along the center of the lower bearing block of the testing machine. Place the cylinder on the plywood strip and align so that the lines marked on the ends of the specimen are vertical and centered over the plywood strip.4. Place the second plywood strip lengthwise on the cylinder and place a 2ˮ x 2ˮ x 14 steel bar over the plywood strip.5. Lower the upper loading head until the assembly is secured in the machine.6. Apply the compressive load slowly and continuously until failure. The rate at which the…
