Bending of a Channel Section Introduction
 This report aims to describe the experiment performed to investigate the stiffness of a channel section, and in particular calculate the flexural rigidity (EI) of the beam by two different sets of calculations based on the results gained in the experiment. The EI of an object is used

quantities calculated in 1969 and with production volumes scheduled for the June 1972 bottling run? Please follow the scheme below to answer this question: a. Investigate the original calculation of Setup Cost (denoted by “S” in the case), is there any mistake? b. Similarly, investigate the original calculation of Unit Cost “C” and Carrying Cost Percentage “K”, is there any mistake? c. Is there any change in demand

14 Philip Chen, Choco Huang, Ariel Chou, Matt Krieger In this report we analyzed Cohen’s approach in calculating WACC. After observing how Cohen derived his figures we came up with our own WACC, terminal value, and EPS. Cohen broke down his calculations into five parts 1) Single or Multiple Costs of Capital 2) Proportion of capital from debt and equity 3) Cost of Debt 4) Cost of Equity 5) WACC In part one; we disagreed with Cohen where he decided to value the company as a

Should calculator be used in beginning algebra class why or why not? There are pros and cons about using a calculator in the course of beginning algebra. We are not going to deiced weather or not calculator should be used, we will decide at what points should they be used. In order to do that we will discuss the pros and cons of calculators in beginning algebra. What are the pros of using a calculator in this course? There are three main pros of using a calculator in beginning algebra. The three

for skilled or experienced people but also for the common man. Although, Mathematics is the study of numbers or quantity, it has been a crucial tool in our daily life. Like, making purchases, travelling, taxes, insurance all require mathematical calculations. As a consequence, Mathematics is a prime vehicle for the evolution of logical thinking and other professional skills

process: To get the calculation of the total selection process, I calculated the total number of each group that passed the test and interview. This number is now divided by the total number of applicants. The last step is to apply the four fifths rule. African Americans: 5/36 = 0.13888 = 13.9 %; 4/5 Rule = 13.9 / 30.9 = 0.44983 = 45% This calculation shows the evidence of adverse impact. Hispanics: 22/102 = 0.21568 = 21.6 %; 4/5 Rule = 21.6 / 30.9 = 0.69902 = 69.9 %. This calculation also shows that

Problems 5-1 through 5-2 (Graded) 5-1 Earned Value Calculation Your project has four activities. Below is the current status of each activity. Activity A was to have cost $150,000 when complete. Its costs so far are $45,000. It is 35% complete. The activity has completed 5 weeks of a planned 15-week schedule. Activity B is at the end of week 2 of a planned 4-week effort. It is 45% complete. It was to cost $100,000 when finished. Its costs to date are $50,000. Activity C is finished

Analysis of Reliability Calculations in Mobile Ad hoc Networks Sai Charan Goud Kolanu, Tejaswi Reddy Karemma Department of Computer Engineering and Computer Science California State University, Long Beach Abstract With the increasing dependency on wireless networks, the need for proper reliability analysis for Mobile ad hoc networks (Manets) is also increasing. Failure of Manets in areas like warfare, nuclear reactors, medical equipment and airplanes can lead to catastrophe. Unlike traditional

problem could be fairly easy, but the numbers are hard to work with or had fractions in them. On this test, calculators were permitted and were a huge help to me. This tells myself that I need to get better at mental math to save time on tests and to not rely on calculators so much. Mental math has always been difficult for me, but mastering it can be greatly beneficial to my math. The test can be taken online or in person, it is really up to the person. I personally would prefer an in person test

Cost of Capital for Marriott Mentioned Tables Not Included Objective: 1) Calculate the divisional and the company cost of capital and explain the calculation. 2) Evaluate Marriott's use of company cost-of-capital rate for the individual divisions. Cost of Capital for Lodging Division can be expressed as CC = We*Ce + Wd*Cd. For the weights of debt and equity (We and Wd), the 1988 target-schedule rates of debt-to-assets and debt-to-equity were used as the only measures available
