Background and Theory This laboratory experiment investigates the surface tension of different working fluids and how contamination can drastically affect surface tension. Surface tension is a result of the molecules deep within the fluid repelling each other while the molecules at the surface attract each other [1]. Introducing contaminates like detergents into the surface of…
Background and Theory The object is to determine how the density, kinematic viscosity and dynamic viscosity of a sucrose solution, as the concentration of the solution are varied. Density is defined as ratio between the mass over the volume. [1] The expected outcome of this experiment is that there will be a correlation between concentration…
Buckling is a physical occurrence observed in slender structures, such as columns, beams, rods or panel; when it undergoes bending due to applied loads, leading to eventual buckling. This phenomenon can result in the complete failure of the structure. Buckling occurs when the applied load surpasses the structure’s buckling load, which represents the maximum load…
What is the importance of beams? The primary function of beams, regardless of the application, is to act as structural elements that transfer loads. In the civil engineering field, beams refer to horizontal elements which symmetrical sections, such as an i-beam. For example, in a building, beams support the weight of a building’s floors above, ceilings,…

Objective To determine the normal stresses in the pressure vessel, and also to observe and material properties of the pressure vessel used. Finally, compare the calculated and measured stresses on the surface of the cylindrical pressure vessel subject to torque while pressurized. Known & Assumptions Materials: The materials required: Technovate Stress Analysis System Model 9800…
What is an example of torsion force? An example of a torsional force would be anytime a force acting on an object results in a twisted or rotating motion. This twisting movement happens when an applied torque or force encounters an opposing force which generates shear strain. This opposing force could be a result of…
Objective To find and familiarize the stresses in the truss due to an externally applied load, and to see how geometry affects to stresses in the truss. Finally, the last goal of this experiment was to become familiar with strain gauge measurements. Known & Assumptions: Materials: The materials required: The triangular trusses Tinius Olsen Testing…
The Charpy impact test, also commonly referred to as the Charpy V-notch test by material scientists, serves as a standardized high-strain rate examination to quantify the energy absorbed by a material upon fracture. The absorbed energy functions as an indicator of the material’s notch toughness. Widely employed in various industries, this test is favored for…
Tension test, alternatively referred to as tensile testing or uniaxial tension test, is one of the most commonly used tests to determine important material parameters such as Young’s modulus, yield strength, ultimate strength, elongation at break, Poisson’s ratio, and Lankford coefficients (R-values). Tension testing constitutes a foundational test in materials science and engineering, involving the…
