In a test to determine the crushing characteristics of a packing material, a steel cone of mass m = 2.6 kg is released, falls a distance h = 700 mm, and then penetrates the material. The radius of the cone is proportional to the square of the distance from its tip. The resistance R of the material to penetration depends on the cross-sectional area of the penetrating object and thus is proportional to the fourth power of the cone penetration distance x, or R = kx4. If the cone comes to rest at a distance x = 28 mm, determine the constant k in terms of the test conditions and results. Utilize a single application of the work-energy equation.

ngr. Beleric measured a distance line using a 20m length of stainless steel tape measure. The line's length was determined to be 396.84meters.The temperature was 10 oC during the measurement, and the tape was supported on both ends.The tape has a cross sectional area of 7.20mm2 and a modulus of elasticity of 200GPa. The tape is 0.095 kg/m in weight. k = 11.6 x10-6 m/C If the engineer determined the lengths of the Temperature correction, Pull correction, and Sag Correction to be 1,197.23μm, 285.53 μm, and 2.23 mm, per segment, Calculate the 20m tape's standard pull in kilograms.
A baseline was measured using a 100m tape which is standardized 15oC with a standard pull of 10kg. The recorded distance was found out to be 430.60 meters. At the time of measurement the temperature was 20oC and the pull exerted was 16 kg. Determine the true length of the base if the weight of one cubic cm. of steel is 7.86 gr. Weight of tape is 2.67kg, E = 2 x 106 kg/cm2, K = 7x10-7 m/oC.
