E-2.- 4.5 m 5 m €= 0.7, S=0.85. w= 28% Muestre la distribución del esfuerzo total, el esfuerzo efectivo y la presión de poros con la profundidad para el perfil del suelo mostrado en la Figura P7.12. Despreciar la acción capilar y la presión de poro del aire. FIGURE P7.12 E-3.- Si el agua del subsuelo en el problema E-2 ocurre: (a) subiera a la superficie, (b) subiera 2 m por encima de la superficie, y (c) descendería rápidamente de 2 m sobre la superficie a 1 m por debajo de su nivel actual, determine y trazar las distribuciones de los esfuerzos verticales efectivas, totales y la presión de poro con la profundidad.

Lion heen construcied belweh the mainland and an island The total cost areluding tolls) to travel across the bridge is expressed as C- 50+0.5V, where Visthe ber o veh/h and C'is thc cost/veh in cents. The demand for travel across the bridue is V 2500-10C O Determine the volume of traffle across the bridge. a toll of 25 cents is added, what s the volume across the bridge? What volume Would be expected with a 50 cent increase Aelbooth is to be added, thus reducing the travel time to cross the bridge. The new nction is C- 50 + 0.2V. Determine the volume of traffic that would cross the bridge. d Determine the toll to yicld the highest revenue for demand and supply function in part (a), and the associated demand and revenue.
