#### Drawing Tender Package

One of engineering company providing drawings at the end of the Month. I have emailed set of questions to engineering company to include every thing in the drawings tender package. I just do not want to miss any question.....If I did not include any questions which might you come across let me know....

#### Determine the most economical and safe design

An axial load P is supported by a short W8 X 40 column of a cross-sectional area A = 11.7 in2 (inches squared) and is distributed to a concrete foundation by a square plate as shown (in the attachment) Knowing that the average normal stress in the column must not exceed 35 ksi and that the bearing s...

#### Determine the concrete footing of an axial load

A 20-kips axial load is applied to a short wooden post which is supported by a concrete footing resting on undisturbed soil as shown. Determine the size "b" of the concrete footing if the average bearing stress on the soil is not to exceed 30 psi. a. b = 25.8 in. b. b = 22.4 in. c. b = 18....

#### Penalty Cost Calculation

Having problems calculating the penalty cost. Please see attached. The U.S. Army Corps of Engineers issues purchase instructions informing potential suppliers that roadway graders will be evaluated using the following life cycle cost model: LCC = unit operating cost, dollars ...

#### Determining Cost Estimating Function

A product plant is being considered for a new booming market. Total fixed cost for design, land, and plant construction is \$105. The variable cost of producing product is a function C (n) = 100n - 3 x 10-3 n2 + 10-7 n3 where n = number of product produced. (a) Determine the total cost function...

#### Deflection of a Beam

If a beam of lenght L is fixed at the ends and loaded in the centre of the beam by a point load of F newtons the deflection at a distance x from one end is given by : y= (F/ 48Ei)(3L^2x-4x^3) Find the position and the value of the maximum deflection of the beam if; L = 10 m Ei= 300x10^6 Nm^...

#### Bending moment in a timber beam

The bending moment in a timber beam M, at a point at a distance x from one end of the beam given by the formula :- M=½{wx(L - x) } Calculate the values of x when M =50Nm, w =5N/m and L =20m --- (See attached file for full problem description)

#### Base isolation technique

Base isolation technique has become the method of choice for structural design of buildings and bridges located in highly seismic areas in recent years. Please provide of an overview of this approach. Also, discuss the application of rolling type bearings for equipment isolation.
