In the following table there are seven tasks, labeled a through g. Some tasks can be done concurrently (a and b) while others cannot be done until their predecessor task is complete (c and d cannot begin until a is complete). Additionally, each task has three time estimates: the optimistic time estimate (O), the most likely or normal time estimate (M), and the pessimistic time estimate (P). The expected time (TE) is estimated. Create Gantt chart and estimate critical path Time estimates Expected time (TE) Activity Predecessor Opt. (O) Normal (M) Pess.

Scenario You are assigned a role as a mechanical engineer for a vehicle design manufacturing company. Your department has a software to perform numerical differentiation and integration. To be able to verify the results of using the software and validate these results, your department manager has asked you to analytically perform some tasks to validate the results generated by the software. Q: is the last two digits of your student Id number. If your number is (20110092) then Q=92. P: is the last digit of your student Id Number. If your number is (20110092) then P=2, If that digit equals zero then use P=1. Example: If your number is (20110040) then P=1.

You own a wheat warehouse with a capacity of 20,000bushels. At the beginning of month 1, you have 6,000 bushels of wheat. Each month, wheat can be bought and sold at theprice per 1000 bushels given in Table 46.The sequence of events during each month is as follows:a You observe your initial stock of wheat.b You can sell any amount of wheat up to your initialstock at the current month’s selling price.c You can buy (at the current month’s buying price) asmuch wheat as you want, subject to the warehouse sizelimitation.Your goal is to formulate an LP that can be used to determine how to maximize the profit earned over the next 10months

The gross requirements for item Z are specified for the beginning of weeks 1 through 8 in the table that follows. Gross Requirements for Item Z 1 2 3 6 7 8 Week 4 Gross Requirement 180 90 180 0 360 0 90 90 The lead time is 2 weeks. The current on hand inventory, at the beginning of week 1 is 360 units. If the order cost is $540 per order and the inventory cost is $3 per unit per period, and the order quantity is the computed part period (or a multiple of the computed part period) when it is necessary to place an order, what is the total cost for the 8 week period? Report as a whole number with no commas. Answer: The correct answer is: 4590
Posted below is a picture of a data table and a diagram of an experiment. In the experiment you rolled a marble down a ruler ramp off the end of a coffee table to observe projectiles and conservation of energy. You do 3 trials for each initial height. Each height is measured in meters. h= initial height of marble off of table Y= height of table off floor X= horizontal distance marble goes from edge of table to where it strikes the floor a) use the table to find information you need to solve for theoretical range and % of error in measured range.
A certain system contains three branches in parallel. One branch contains units A and B in series. A second branch contains units C and D in series. The third branch contains unit E alone. These non-identical units have constant hazard rates in order of their unit number of 0.1/year, 0.15/year, 0.2/year, 0.15/year, and 0.25/year. a) Draw a block diagram and compute the reliability of the system from the reliabilities of the individual units. b) Draw a signal flow graph. c) Identify the cut sets and the minimal cut sets. d) Find reliability of the system. e) Find the mean time to failure

For all the following problems, a) b) 4. You need to show at least 3 iterations calculated manually with all steps. You do not need to include the M.files for the bisection method (bisect.m) and for false position (falspos.m). You must, however, show the command lines for the given functions with their variables and other parameters. Zero-pressure specific heat of dry air Mechanical engineers, as well as most other engineers, use thermodynamics extensively in their work. The following polynomial can be used to relate the zero-pressure specific heat of dry air cp kJ/(kg K) to temperature (K): 11 0.99403 +1.671×10-4T + 9.7215-10-8T²-9.5838×10- Cp = T3+1.9520×10-14T4 (a) Develop a plot of cp versus a range of T=0 to 1200 K. (b) Use bisection to determine the temperature T that corresponds to a specific heat of 1.1 kJ/(kg K). (c) What will be the value of T if you use false position method? (d) What is the percentage error between the results of (b) and (c)? For both methods use maximum…
