The vertical stress at a point in soil is σx =400 kN/m², Txz = 50kN/m² while the
horizontal stress at the same point is σ =100 kN/m², Tzx = -50kN/m².
(a) Draw the Mohr circle that describes the 2D stress state at the point.
(b) Find the maximum shear stress that acts at the point and its orientation angle
from the horizontal plane.
(c) Find the principal stress (σ₁ and σ3) that acts at the point and locate the major
principal stress plane and its orientation angle from the horizontal plane (Use the
pole method).
(d) Determine both the normal and shear stress at a plane that orientates from the
major principal stress plane with an angle of 30° (counterclockwise direction) and
verify your results with the stress transformation equations.

Given: H = 1m; Angle φ = 60⁰; q = 2.4 kPa.1. Determine the normal stress (MPa) in strut AB with crosssectional dimension 6 mm x 50 mm.2. Determine the normal stress (MPa) in strut BC with crosssectional dimension 8 mm x 40 mm.3. Determine the required diameter (mm) of pin (under double shear) to be used in A or C if the allowable shear stress of the pin is 120 MPa.

Initially, the capacities of routes 1 and 2 are 4000 and 2000 veh/h, respectively. A reconstruction project on route 1 reduces the capacity to 3000 veh/h, but total traffic demand is unaffected. Observational studies note a 35.28-second increase in average travel time on route 1 and a 68.5% increase in flow on route 2 after reconstruction begins. User-equilibrium conditions exist before and during reconstruction. If both routes are always used, determine equilibrium flows and travel times before and after reconstruction begins.arrow_forward8.19 Three routes connect an origin and a destination with performance functions t₁ = 8+ 0.5x1, t2 = 1 + 2x2, and t3 = 3 + 0.75x3, with the x's expressed in thousands of vehicles per hour and the 's expressed in minutes.
