What are the geological consideration for the selection of Dam and Reservoir site?

With the aid of a sketch, explain what is lateral torsional buckling of a steel beam, when it might occur, and what a structural engineer would do about it.

What is the checking regime for a permanent scaffold on a construction site?

Why are the slabs for composite construction designed as simply supported rather than continuous?

Alan offers, on day 1, to sell a book to Bob for $100. He then changes his mind and puts a revocation letter in the mail on day 2. Bob puts a letter in the mail on day 3 accepting the offer, and then on day 4 receives the revocation letter. The most accurate statement concerning the contract implications of this is

Group of answer choices

a contract has been formed on day 1

a contract has been formed on day 2

a contract has been formed on day 3

no contract has been formed

Question 101 pts

Mark says to David "If you walk across the Brooklyn Bridge on April 30, I will pay you $100." David agrees to do this but then changes his mind and does not walk across the bridge on April 30. Of the following statements, the most accurate one is

Group of answer choices

David has breached a contract

David has not breached a contract because he was never paid $100

David has not breached a contract because there was no consideration

David has not breached a contract because there was no acceptance

Question 111 pts

Suppose that, in the preceding question, David starts to walk across the Brooklyn Bridge but after he has completed three-quarters of the walk, Mark says to him "I revoke my offer." At this point in time,

Group of answer choices

there is no longer any contract because the offer has been revoked prior to acceptance

Mark has breached a contract with David to pay him $100

Mark's revocation is not effective because David has started to walk across the bridge

Question 121 pts

Suppose that, in the previous two questions, David never tells Mark that he will walk across the Bridge, but on April 30 he does so. The most accurate statement below is

Group of answer choices

Mark owes David $100 because a contract was formed and David performed his contractual obligations

Mark does not owe David $100 because David never formally accepted the offer

Mark will only owe $100 if David can prove that Mark knew he was going to walk across the Bridge

Mark does not owe David $100 because Mark is not getting anything of value out of the agreement

Question 131 pts

Acme Contractors agreed to build a home for $200,000. The contract called for performance in 80 days, but because of the owner's breach of the contract it took Acme 100 days to complete the contract. During this 100-day period, Acme had another contract, also in the amount of $200,000, and had home office overhead in the amount of $10,000. Acme sues the owner for delay damages. Under the Eichleay case, Acme is

Group of answer choices

not entitled to damages for lost home office overhead because it would have incurred that overhead in any event

entitled to $1,000 in lost home office overhead

entitled to $5,000 in lost home office overhead

entitled to $10,000 in lost home office overhead

Explain Thomas model and the parameters (A, B, C and D). Discuss

Calibration and Validation process and why do you need Excel-based Solver for

Calibration. Is Thomas model a simulation model? Explain. Is it conceptual,

physical or empirical model?

Assuming the following information is known about two lines, compute the coordinates of the intersection of the two lines (all information in feet).

Line AP (Where Point P is the Point of Intersection)

Point A (N,E) = 5016.07, 5020.42                  Bearing AP = S 44^o 59' 47" W

Line BP

Point B (N,E) = 1671.56, 5487.06                  Bearing BP = N 56^o 33' 17" W

1. A 3.5 m clear span singly reinforced cantilever beam has a rectangular section of b=300mm and D=500
mm is reinforced with 2 bars of 32 mm diameter and 1 bar of 25mm diameter in the tension zone. The
live load taken by the beam is 19 kN/m. Check if the beam is safe to carry the above load . Use M25
and Fe500.

Name any FOUR factors that influence the slope of a statically determinate beam. Mention how they affect the slope of beams.

Three different anchor bolts were installed in a 12" -2500 PSI concrete strength slab. The bolts were all 1/2 diameter with 6" embedment depth. The types were mechanical, epoxy, and cast in place during original pour.

which anchor bolt would you predict would take the greatest force to pull out from the slab and why

Explain does why:

• On the basis of qual workability the surface characteristics of aggregate have a limited impact on the ultimate strength of concrete.

• the surface characteristics of aggregate have a clear impact on ultimate strength of concrete on the basis of qual water content.

• The cylinder strength is higher than that of cube's.

• The aspect ratio of concrete cylinders has no impact on compressive strength obtained in compression testing machine with brush platens.

• Concrete bridges should not be subjected to stress levels higher than 0.55 of ultimate strengths.

• the maximum aggregate size of aggregate have two opposing effects on concrete strength.
