Study of deformable bodies will help researchers integrate the set parameters in a pontoon bridge to designing the pontoon bridge. Experiments can be done to acquire “strength” of materials. The objective of this stage is to specifically acquire strength, stiffness, and stability of a body. The experiment must be designed to help the researcher understand the reaction of a pontoon bridge’s strength, stiffness, and body stability to certain external loads and projective external loads. Projective external loads are assumed to be the maximum external forces that can occur in the pontoon bridge.
At the system level, the probability of the entire ERP system usage failure can be obtained by quantitative evaluation of the fault tree, thus making it possible for executives of the hosting organisation to make informed decisions on ERP project initiation, termination and high-level system requirement and scope changes. At the component level, the implications of fault tree analysis depend on the approach that was adopted in fault tree construction. There are two basic approaches, which a third one is the mix of them. The difference in these two approaches is that the second requires one to incorporate the root causes to component failures into the fault tree and thus directly assess the impact of these root causes on system failure, while the first approach indicates that the causes are either too elusive to be included in the fault tree or will be identified on a later
It was observed that the general width of the anterior talofibular ligament does not show much variation and the variations that were noted posed no impact to the function of the ligament. At the anterior border of the lateral malleolus the anterior talofibular ligament courses anteriomedially, and it attaches to the talar body directly onto the area where the lateral malleolus is located. The ligament essentially lies parallel to the ankle joint when it is relaxed however during dorsiflexion the ligament rises, and during plantar flexion it declines. The superior band is a slacked while the inferior band is tensed during dorsiflexion. In plantar flexion, the inferior band is slacked whilst the superior band is tensed.
In general, both the steel toe and composite toe are considered to be safety toes, and are designed to protect your feet from impact, compression and or injury that could be sustained on the job. However, there is a slight difference in the two, and depending on where and how you will use them will make the difference in how you select. Steel toes have been around protecting feet in the work field for many years. The plate situated over the toe area is constructed of heavy-duty steel. Because they are a safety toe OSHA requires them meet ASTM standards, and receive ratings for impact and compression.
The load exerted on the beams will be caused by; the load from the self weight caused by the deck, loads resulted to by the live loads, weight exerted due to car skidding as well as effect of braking and horizontal loads as a result of temperature and movements such as wind. Due to this reason, the beam should be strong enough to carry the load. The design shape of the beam will be as shown below. There are a number of forces that will act on the beams and the bridge thus the beams should be constructed in a way they will be able to
The tensile strength of the material increases because the subsequent application of tensile stress must nullify the compressive prestress. • This can result in improved structural capacity and serviceability compared to conventionally reinforced concrete. • High-strength tendons are used to produce compression. They are made of high- tensile steels, carbon fibers etc. and consist of threaded bars, single or multiple
(Engineers say "Stress is proportional to strain".) In symbols, F = kx, where F is the force, x is the stretch, and k is a constant of proportionality. If Hooke's Law is correct, then, the graph of force versus stretch will be a straight line. Tensile testing experiment Purpose of the experiment: Tensile testing is one of the most fundamental tests for engineering,and provides valuable information about a material and its associated properties. These properties can be used for design and analysis of engineering structures, and for developing new materials that better suit a specified use.The basic idea of a tensile test is to place a sample of a material between two fixtures called "grips" which clamp the material.
V. PROPOSED CONTROL SCHEME The proposed iUPQC control arrangement is an ABC reference structure based control, where the SAF and PAF are controlled in an independent way. In the suggested control scheme, the power calculation and harmonic abstraction are not required since the harmonics, unbalances, disturbances, and displacement would be compensated. The SAF has a current loop in order to make sure a sinusoidal grid current synchronized with the grid voltage. The PAF has a voltage loop in order to ensure a balanced controlled load voltage with small harmonic distortion. The SAF and PAF control loops are independent from each other since they act independently in each active ﬁlter.
Shop primer has two important functions which are preserving the steel material for the final product and aiding in the productivity of process building a ship. Zinc coating systems protect coatings in much the same manner as galvanizing. Then, the process of building a ship is cutting steel. Steel plates are being cut into the parts that will form to the hull and deck sections of the ship. The process of heating and bending a steel plate into curved shapes is of great importance in shipbuilding and requires sophisticated skill and technique.
This paper presents a Fault Tree (FT) based approach for quantitative risk analysis in the construction industry that can take into account both types of uncertainties including objective and subjective uncertainty. In this research, the identified basic events are first categorized based on the availability of historical data into probabilistic and possibilistic. The probabilistic and possibilistic events are represented by probability distributions and fuzzy numbers, respectively. The hybrid uncertainty analysis is then performed through combination of Monte Carlo simulation and fuzzy set theory. The probability of occurrence of top event is finally calculated using the proposed fault tree based hybrid uncertainty analysis method.
