The document discusses several tests used to evaluate the properties of films and packages, including:
- Specular gloss measures the fraction of light reflected from a sample's surface.
- Haze measures the percentage of transmitted light that is scattered by a transparent sample.
- Transmittance measures the percentage of light transmitted through a translucent sample.
- Tear, tensile, and elongation tests measure a material's strength, flexibility, and resistance to tearing or breaking. Impact tests similarly evaluate a material's resistance to breaking from blows or impacts.
- Permeability tests like water vapor transmission measure how quickly gases pass through a material, important for evaluating moisture barriers.

Consolidated Drained (CD) Triaxial Test.pdf
Determination of strength and stress-strain relationships of a cylindrical specimen of reconstituted specimen using Consolidated Drained (CD) Triaxial Test.
1. A series of drained triaxial tests under four different initial states were conducted on Yamuna River sand. The results consist of simple stress-strain relation, change in volume behaviour were plotted.
2. Basic stress-strain relation with volume behaviour was presented in plot. The results for densely prepared sand samples show an expected behaviour. There is a significant difference in peak and residual deviatoric stress (q) as can be depicted form the plot.
3. With increase in confining stress, load carrying capacity of specimen increases.
4. Saturation value ‘B’ must be acquired to be more than 0.95 before starting the isotropic consolidation phase in CD test.
5. CD tests are performed at much slower strain rate as compared to CU tests for the same soil. The strain rate for CD test can be chosen approx. 8-10 times lower than the CU test.
6. It is important to have no pore water pressure generation throughout the shearing phase of CD test or in other words strain rate must be so small that pore water pressure must get dissipated quickly when specimen is subjected to compression loading in CD test.
7. In CD test, volumetric strain versus axial strain relationship shows contractive response for NC soils and dilative response for OC soils. (NC = Normally consolidated, OC = Over consolidated)

Reinforced concrete is a composite material made of concrete, which resists compression well but has low tensile strength, and steel reinforcing bars, which resist tension well. Together they create an economical and strong structural material. The document outlines structural elements, design considerations for safety, reliability, and economy, and limit state design principles which ensure structures do not fail under expected loads. It also discusses factors that affect concrete durability and different failure modes in reinforced concrete depending on steel reinforcement ratios.
Center of pressure and hydrostatic force on a submerged body rev
This document describes an experiment to determine the center of pressure and hydrostatic force on a submerged body. The objectives are to understand hydrostatic pressure distribution and verify the location of the center of pressure. The apparatus is a ring-shaped water vessel mounted on a pivot, allowing measurement of the moment due to hydrostatic pressure. The theory section explains how hydrostatic pressure varies with depth and how this relates to the resultant force and center of pressure on a submerged surface. Calculations are provided for determining these values for the apparatus based on measurements of water level and applied weight. The procedure describes how to set up and perform the experiment.
