The lab methods discussed in class are not the only means of measuring specific gravity- one can also measure the volume of water displaced directly. Suppose you have a sample of sand that displaces 251 cm³ in the SSD state. The sample has an SSD weight of 618 g and an oven dry weight of 599 g. Calculate the bulk specific gravity (SSD), bulk specific gravity, apparent specific gravity, and absorption (dry) of the material.

Question 2 An onshore rig is drilling a production well with drilling pipe with the dimension of 250 mm outer diameter and 130mm inner diameter, see Figure 2. When drilling the drilling pipe, suddenly hit a bedrock which cause the drilling operation stop, see Figure 2. The drilling pipe is made of steel with the modulus of elasticity of 200 GPa and coefficient of thermal expansion is 11.7x10-6/0C. Assuming the initial temperature of the drilling pipe is 27°C and final drilling pipe temperature is 80°C, compute: a) the reaction force at point A and B 130mm Tracing h Snel S 250mm Kelly Sandstone 3500m b) Normal stress exhibit by the drilling pipe c) Is normal stress exhibit compression or tension? 2cm Bedrock 500m F000kN

A selected powder has a true density of 3.5 g/cc. Experimentally, 2.5g of the powder measures 40 mL in a cylindrical graduate. Calculate the true volume, void, porosity, apparent density and bulkiness.

Three samples of aggregates were taken weighed in moist and dry condition. Moist Dry Unit Unit Absorption Volume Aggregate Wt. Wt. (%) (m³) (kN/m) (kN/m³) Sample 1 23.425 20.018 5.14 0.366 Sample 2 22.7 18.757 3.87 0.695 Sample 3 20.292 18.387 2.62 0.237 Where; Unit weight of water = 9.81 kN/m3 Determine the average free moisture content of the three samples.
