1 The Base Of Machine Is Supported By Four 4 Two 2 Leg Supports Like A Shipping Cont 3951371

1. The base of machine is supported by four (4) two (2) leg supports (like a shipping container crane) consisting of 2.4m long steel struts pinned at each end. The machine must remain level and aligned at all times. Due to a maintenance issue, one of the 20mm square struts is replaced with a 20mmx50mm titanium one.

1a. What is the result of this on pin “C”

————————————————————

2. A 500ft length of 3/4”-6×37 class bright wire rope EIPS IWRC (steel cable) is to be used to suspend some lights across a football field. It is attached to adjustable eye bolts at each support. Each eye bolt has 12 inches of adjustment available. The bolts are exactly 500 ft apart to start.

2a. How far do you need to loosen the eye bolts to initially hang just the cable? (Note: it may help to treat the distributed load as a point load at the middle with the cable acting as two thin rods initially 250 ft long)

2b. What is the final position of the bolts in order to have the cable “sag” less than or equal to 6 inches after the light) is attached?

Note Hibbeler Mechanics of Materials 10th Edition R3-4 and R3-5 may help you. Attached.

3. A steel process component is mad by welding three (3) pipes to two (2) pre drilled steel end plates. Due to a serious lack of caffeine, the center pipe is cut 0.35mm short. The worker decides to fix the problem by forcing the ends together in a large vice and then welding the center pipe (B).

3a. What is the stress in each pipe after it is removed from the vice? (Neglect any welding stress)

Note that triangle thing (all connections) on C is a welding symbol for a 6mm fillet.

3b. Discuss/explain what this did to the capacity of the finished part.

1 The Midnight Hour A Local Nightclub Earned 100 000 In Accounting Profit Last Year 1040006

1)The Midnight hour, a localnightclub, earned $100,000 inaccounting profit last year. Thisyear the owner, who had invested $ 1million in the club, decided toclose the club. What can you sayabout economic profit (and the rateof return)in the nightclub business?ANSWER:Economic Profit = TR(total revenue)-TC(total economic cost)EP = $100,000 – $1,000,000EP = -$900,000Since EP is a negative number thefirm should shut down, the output isnot positive, therefore the companyoperates at a loss, the managerneeds to determine how long theywant to continue with this lossprocess.Does this sound like the correctanswer?Thanks,EY

1 The Traveling Salesman Problem Tsp Is A Famous Problem For Which There Is No Known 2835377

1. The Traveling Salesman problem (TSP) is a famous problem for which there is no known,

tractable solution (though efficient, approximate solutions exist). Given a list of cities and the

distances in between, the task is to find the shortest possible tour (a closed walk in which all

edges are distinct) that visits each city exactly once.

Consider the following algorithm for solving the TSP:

n = number of cities

m = n x n matrix of distances between cities

min = (infinity)

for all possible tours, do:

find the length of the tour

if length

min = length

store tour

a) What is the worst-case (big-O) complexity of this algorithm in terms of n (number of

cities)? You may assume that matrix lookup is O(1), and that the body of the ifstatement

is also O(1). You need not count the if-statement or the for-loop conditional

(i.e., testing to see when the for-loop is done), or any of the initializations at the start of

the algorithm. Clearly show the justification for your answer.

b) Given your complexity analysis, assume that the time required for the algorithm to run

when n = 10 is 1 second. Calculate the time required for n = 20 and show your work.

2. Suppose an algorithm solves a problem of size x in at most the number of steps listed in each

question below. Calculate the asymptotic time complexity (big-T or big-theta) for each example

below. Show your work, including values for c and x0along the way.

a) T(x) = 1

b) T(x) = 5x – 2

c) T(x) =3x^3+ 2 + x2

d) T(x) = log (x * 2x!)
