8. Describe the importance of this order. Include affect on force of contraction and fatigue. This order is set up in order to increase the amount of force necessary for the work load while also limiting fatigue. The slow oxidative fibers are set up to help with weaker amount of force but are very resistant to fatigue.
Fiber cabling is growing very fast due to how much more efficient it is than copper cabling. Fiber, for one, has a greater bandwidth. Single mode cables offer the most bandwidth but you have the option of the single mode, 62.5 or 50 micron multimode cables. In addition to that, fiber can carry more information than the copper. Fiber can also carry over a longer distance with low attenuation.
(4 points) q = m × c × Δt Given: q=? m = 34.720g c = 4.18 j/(g x °C) Δt = 41.6°C - 25.2°C = 16.4°C q = (34.720g) (4.18 j/(g x °C) (16.4°C) q = 2380.13j You are trying to figure out the energy change of the water which is the surroundings in the lab. To do that you must take the mass of the metal, which for me was Aluminum, and multiply it by the heat capacity of the water, which was given, then multiply that by the change in temperature, which is the final temperature of the mixture
Effect of Local Steel Slag as a Coarse Aggregate on Properties of Fly Ash Based-Geopolymer Concrete O. M. Omar, A. M. Heniegal, G. D. Abd Elhameed, H. A. Mohamadien Abstract—Local steel slag is produced as a by-product during the oxidation of steel pellets in an electric arc furnace. Using local steel slag waste as a hundred substitutes of crushed stone in construction materials would resolve the environmental problems caused by the large-scale depletion of the natural sources of dolomite. This paper reports the experimental study to investigate the influence of a hundred replacement of dolomite as a coarse aggregate with local steel slag, on the fresh and hardened geopolymer concrete properties. The investigation includes traditional testing
This transfer allows quantifying the influence of blasting waves on the rock mass of the slope and on soil slopes. In this paper, the effects of waves’ frequency and Rayleigh’s surface waves are discussed as well as the slope characteristics such as its rock mass. Transfer of Analytical Techniques from Earthquake Engineering The similarity between blasting vibrations and earthquake motions is known. A simple example is the use of blasting-induced vibrations in experiments built to predict earthquake response of a building structure. According to Dowding (1988) two levels of analysis can be considered.
This is just to avoid the hot steel damaging the table. Now turn the fan on and face it towards the block of steel. The fan will cool the steel down. Using the digital thermometer record the temperature of the block of steel every minute. These temperatures are the actual temperature.
A straight line approximation for the Mohr-Coulomb failure envelope can then be drawn. The friction angle is thus calculated from the slope of the failure envelope. As with any experiment, the more tests taken for different normal stresses, the more accurate the Mohr-Coulomb failure envelope will be. Experimental Procedure * Weigh the initial mass of soil and record it. * Measure the height, width and length of the shear box and record it.
For example, sand can be moved easier than silt or clay, as fine- grained particles tend to be more cohesive. The material carried by the river or the capacity is responsible for most of the subsequent erosion. The mean fall or settling velocity curve shows the velocities at which particles of a given size become too heavy to be transported so therefore the sediments would be deposited. The graph on the previous page shows two important points which are that sand can be transported at lower velocities than either finer or coarser particles. During times of high discharge and velocity, the size and the amount of the river’s load will increase considerably causing increased erosion within the river’s channel.
28 October 2008 Introduction: Static and kinetic friction are forces that are a result of two surfaces in contact with each other. Static friction is the force that must be overcome to cause an object to begin moving, while kinetic friction occurs between two objects in motion relative to each other. The kinetic friction force, Ff, kinetic, is defined by Ff, kinetic = μkFN, where μk is the coefficient of kinetic friction and FN is the normal force acting on the object. The maximum static frictional force Ff, max static, is defined by Ff, static = μsFN where μs is the coefficient of static friction and FN is the normal force on the object. The maximum frictional force that must be overcome before movement is able to begin is μsFN.
sine, random and shock. A detailed work has been carried out to quantify the mechanical properties of the PCB plate both analytically and experimentally. This E value obtained was used in the FEM analysis (using ANSYS 16) to solve the vibration response of the
