QUESTION 1
First determine whether the structure is statically determinate or indeterminate using 2n= m + r, where n= joints, m= members, r=reactions
In this case, n=11, m=19, r=3 thus 2x11=22=19+3 therefore the structure is statically determinate
Let the length of each of the 5 bays be x,
Determine the reactions at the supports = (1+1+1+1+1)/2 = 2.5 units, simply because the truss is symmetrical about the apex.

...Laboratory Report: Fluid Mechanics— Verification of Bernoulli’s Equation The behavior of the laminar fluid motion along a converging-diverging tube of known cross-sectional area, at different flow rates, is investigated, and the mass as well as energy conservation laws are verified in this experiment. Another objective of performing it is to measure the loss of energy due to viscous resistance to the fluid the motion in case of higher flow rates. The results obtained from the experiment not only verify the basic laws and characteristics of a fluid in motion, but also determines the losses incurred in energy due to resistive forces. Introduction When a fluid undergoes motion, there are certain laws it...

... Number> Software Engineering Question a) List five ways of describing operation logic. Describing logic islargely a matter of great concern as that explains the basic data and control flow within a system for finding the processes that essentially brings forth the identification and management of the supply chain of the system. The following are the various ways in which the operation logic can be described:
1. Flowcharting: It is a very simple visual solution for fetching the flow of control of the system and takes into account the processes and the decision making scenarios.
2. Data Flow Diagram: It highlights the processes and the flow of the raw data and information into the system to derive an objective. It also takes... Number>...

...June 11, 2009 Fluid Mechanics A pipe whose diameter is 10.00 in. is equipped with a pipe orifice. The diameter of the orifice is 6.00 in. Also, piezometers that lead to a differential mercury gage are connected to the pipe 10.00 in. above the orifice and 5.6 in. below the orifice. If the drop in pressure head indicated by the gage at a certain instant is equivalent to 2.27 ft. of water, the rate of discharge for the pipe, in gallons per minute , is

...Physics 300 Lab report: Archimedes Principle Archimedes Principle, which s that the amount of buoyant force on a body immersed in a fluid is the same as the weight of the fluid displaced by the object, was applied in the determination of the density of rocks. Buoyancy is responsible for the apparent weight loss experienced by objects when immersed in fluids other than air.
This experiment was carried with the aid of a spring balance, which was used to weigh the rock samples. The experiment involved the weighing of rock samples in air and then when submerged in water. Water was chosen for this experiment because it has a peculiar property in that 1 gram of water occupies a volume of 1 cm3. This property...

Determine viscous drag of bluff and streamlined bodies
Q3:
(a) Describe the terms skin friction drag and form drag.
On describing skin friction drag and form drag, one ought to comprehend the fundamental ideas accompanying the term ‘drag’. As introduced in fluid mechanics, ‘drag’ pertains to the force exerted on a material by the fluid through which it is transported, either co-currently or counter-currently. It is often referred to as a sort of friction made by the resistance of fluid against an object moving in it. In design calculations for a variety of structures, drag forces are considered to an appreciable extent to figure good material selection and engineering...

Organizations all over the world are facing challenges when it comes to making strategies. This is mainly due to increased completion, regulatory changes, turbulent environment, changes in tastes and preferences of consumers and new technology. In order to study how managers make strategies when faced with uncertainty, the authors take a look a company (CommCorp) which was faced with uncertainty with the emergence of the internet. In order to make itself relevant despite the technological changes, the company had to come up with new strategies. The authors study the events as they unfold... Forecasting:...
