Dynamic Cone Penetrometer

. Penetration Rod A steel rod (usually about 1 meter in length) that penetrates the soil. The rod is marked with graduations (typically in millimeters) to measure the depth of penetration. . Cone Tip A conical metal tip (typically with a 60-degree angle) attached to the lower end of the penetration rod. The cone tip pushes through the soil as the hammer applies force, and its shape ensures consistent soil resistance during penetration.
