Houston 3s Fibre Experiment Report

998 Words4 Pages

Abstract An experimental program was conducted in order to study the strength and behaviour of SIFCON with different types of fibres. The different fibres that were used in this experiment were steel fibre and Recron 3S fibre. The different fibre volume considered was 4, 5, and 6%. The tests that were conducted were compression test, Split tensile test and flexural strength test. The steel fibre used in this study was hooked end steel fibres having 1mm diameter and an aspect ratio of 50. Recron 3S fibre having length of 50.8mm was used. Results indicate that among 4, 5 and 6 percentage of steel and Recron 3 S fibres, 5% showed the optimum value in compression, tension and as well as in flexural strength. For 6%, the results of both fibres showed a decrease in strength compared to 5% …show more content…

Compression test were carried out for cube and cylinder specimen using steel and Recron 3S fibres. A total of 18 cube specimen using steel fibres were prepared for the testing at the age of 7 and 28 days. Another 18 cube specimen was prepared using Recron 3S fiber. Also 36 cylinder specimens were casted using both fibres for the testing at the age of 7 and 28 days. A cube size of 150 x 150 x 150 mm and cylinder size of 150mm diameter and 300mm length was adopted. The specimen was placed centrally in the testing machine. The load was applied uniformly until the specimen fails due to compression. The ultimate load divided by the cross sectional area of the specimen is equal to the ultimate compressive strength. 3.2. Split tensile test The split tensile test was carried out as per IS 5816:1999. A total number of 36 cylinder specimens using steel and Recron 3S fibre were casted. The test was conducted at the age of 7 and 28 days after curing. The size of the specimen was 150mm diameter and 300mm length. The loading was applied continuously at a specific rate until the specimen reaches its ultimate load. 3.3. Flexural strength

    First was the Manual Muscle Testing on both the right and left arms. As expected for her left side, most of her muscles scored in the poor range, however, her right side she had difficulty in her pectoralis muscles extending her arm upward and outward. Finally, the grip and pinch strength test showed that her left hand has no strength in it, but her right hand scored

There are 2 type of network cabling which is Thicknet and thinnet (diameter is about 0.25 inches or 0.64 cm) this can be used to connect any type of the network cables. Thicknet cabling is referred 10base5 system which is 10 Mbps of speed and 500 meter of the distance but the Thicknet cables is used for LAN network. Thinnet cable referred 10base2 which is 10 Mbps and 200 distances and it’s used for LAN network.

Professionals such as doctors, nurses, physical therapists, athletic trainers and personal trainers use this book to search a specific muscle in the body to find a correct test to evaluate a particular muscle. Each chapter offers an expanded treatment and exercise sections to be able to evaluate personal injuries or pains suffered from training. Each chapter goes over a particular section of the body starting out with chapter one being about posture to the last chapter being lower extremities. It explains each muscles purpose, preforming test and proper treatment of each muscle and muscle

    Decreases in voluntary torque generation at the extremes of the functional joint range of motion (0° to90° flexion) may be attributed to mechanical and/or muscle activation factors. Also as discussed, at this extended range the muscle is not at optimal length and the numbers of actin sites available for cross-bridge binding is limited. Brownstein et al. (1985) found that peak torque was coincident with maximum IEMG at 50° for males and 70° in females of knee flexion. With Subject 1’s (male) maximum quadriceps isometric contraction occurring at a 60° knee joint angle and Subject 2’s (female) occurring at 75°, our results correlate quite closely with these

    Just as we found, this study concluded that the back squat resulted in higher compressive forces than the front squats. This study as well as our group project, both used the bar, to assist in the squats. This study also used males and females. However, these individuals were experienced at performing front and back squats, which was different from our project. The same muscle groups were measured as ours (rectus fermoris and bicep fermoris).

    Light Refraction Lab Final Write-Up When light passes through any obstacle, it is affected in different ways, especially when the obstacle is transparent. In this lab, the objective was to show students what happens when light passes through water. “When light refracts into a substance in which it must slow down, the light ray will bend toward a line perpendicular to the surface it strikes” (Wile). Water forces a light ray to slow down, and so the light ray will bend.

    I had first formal exposure to civil engineering in course “Architecture 1”. This course provided me the fundamental concepts of civil architectural principles such as designing procedure, architectural component’s layouts, functional spaces as well as environmental impacts. To strengthen my concepts I pursued the courses “Strength of Materials”, “Structural Mechanics” which gave me essential knowledge about the external and internal forces occuring in simple structural elements under action of various types of loading as well as fundamental concepts in structural analysis such as modellisation, classification of structures. I gained valuable exposure to the analysis of simple structures submitted to compound loadings by the application of the principle of superposition for such cases as: unsymmetric bending, combined bending and tension or compression, combined bending and torsion, general compound loading. Futhermore, I was fascinated by the force method and displacement method for analysis of statically and kinetically indeterminate structures.

    The load on the beam was then unloaded to zero in increments of 10 kg and all 6 strain gauges were then again recorded at each increment. Results: (i) The graph produced a straight line when the specimen was loaded up to 6 kN. The specimen was then unloaded to 0 kN again. This produced a straight line returning to the same place, the origin. The specimen was then loaded up to 11 kN and unloaded again.

    Table 1: 2024T351 Specimen Experimental Data The experimental ultimate tensile strength of 65,507.15 Psi is relatively close to the typical tensile strength of 64,000 Psi with 2.35 percent error. The experimental young's modulus of 10,644,380 Psi is close to the standard elastic modulus of 10,600,000 Psi with 0.42 percent error. Using the graphs, the yield stress was found using a 0.2% offset. The yield stress was found to be about 50,000 Psi, far from the standard 42,000 Psi. This resulted in a 19.05 percent error.
