Draw the given truss with all zero-bars removed. If the structure is stable and statically determinate, solve the forces in all of the bars of the truss using hand calculations. Indicate tension (T) or compression (C). If it is stable and determinate, check your answers using Risa 2D eductional software and print out a screenshot of the deflected shape.
Write the equations for shear and moment between support A and B (Selection the origin at A) and Draw the S . F .D) and B.M D with peak values indicated in the diagrams.
The pavement structure consists of 160 mm of hot-mix asphalt (HMA), 150 mm of granular base and 450 mm of subbase placed over silty clay subgrade. The pavement is 20 years old and its current PCI is 50.

A two stage rocket with a total mass of 925kg is traveling at a speed of 6.6 10^3 m/s away from the earth . A predesigned explosion separates into two sections of equal mass that move with a speed of 2800m/s relative to each other along the original ..
A simple steam power plant operates at steady state with water circulating through the components with a mass flow rate of 100 kg/s. Stray heat transfer, kinetic energy and potential energy effects are negligible.
If they plan to increase their savings by 5% each year, how much must they invest in the first year given that they expect to earn 4% per year on their investment?
Repeat LEM(Limit Equilibrium Method) analysis in clay (undrained) using a circular failure surface, with the center of the circle a distance h above the edge of the footing. What ratio of h/B gives the minimum value of Nc? How does this compare with ..
