if the truss structure is inverted, explain how this effect on the truss forces and when this geometric arrangement can used in structural schemes ?

10 examples of engineering mechanics in our daily lives?

- A primary sedimentation basin for a municipal waste water treatment plant treats a flow of 3 MGD and removes 70 percent of the total suspended solids..The basin is 60ft in diameter with a depth of 15 ft. the TSS removed (kg)in the basin about ?

A cantilever beam 4m long carries a uniform load of 3.5 kN/m over a portion 1.5m from the free end. E = 200 GPa and I = 30 x 10^6 mm⁴

Using AMM (Area Moment Method):

1. Determine the rotation at the free end.
2. Determine the deflection at the free end.

What kind of rebar would be most cost effective for foundation? Would it be to design for the smallest diameter of rebar and largest amount of distance O.C.?

If water is seeping, the effective stress at any point in a soil mass will be different from the static case. It will decrease or increase depending on the direction of seepage. With help of sketches, describe what will happen to effective stress if the water is seeping downward through a soil layer.

Give two examples of how ductility can be used to analyze a statically indeterminate structure at its strength limit state, as though it were statically determinate.

In a two – story building, an exterior column is to be designed for a service dead load of 1000 KN, maximum live load of 1500 KN, dead load moment of 60 KN m, and live load moment of 90 KN m. If the column dimensions will be restricted to 400 mm x 500 mm, fc’ = 27.6 MPa, and fy = 414 MPa, calculate the required column reinforcement.

Topic - Construction: Structural, loads, tension

1.) Explain why pure tension members are the most efficient structural types for carrying building loads?

2.) How structural members behave when they are subjected to tension, compression, torsion, and bending forces in structures.

Design a rectangular tied column for a DL = 1000 KN and a LL = 1350 KN. It also carries a ???????? = 20 KN m and ???????? = 40 ??. ?ℎ? ?? ′ = 27.6 ???, ?? = 414 ???.

A zenith angle was measured six times with both faces of a total station. The average direct
reading is 86°34′31″ with a standard deviation of ±12.8″. With the reverse face, it was
observed as 273°25′12″ with a standard deviation of ±8.8″. What is the most probable value
for the zenith angle in the direct face?

Superstructure Frames: Construction

Using all the different "design types" of superstructure frames (Concrete frame, Timber Frame, Steel Frame), how would you "design/build" a high-rise in your area (California, Fresno), and what types of structural systems would you use? You may make geographical assumptions to fit your model building.

According to superfund (CERCLA), what is the formal steps to follow in the cleanup process? How much is the current EPA budget for the Superfund program? How the regulations are applied for recouping cleanup costs?

What are the three forms of communications for engineers?

Explain the importance of data collection and information research on a project outcome.
