La figura muestra la estructura de un panel publicitario digital (Pilar tubular cuadrado hueco y cimentación de concreto armado de peso equivalente a 3.5 veces el peso de la superestructura). La pantalla led es de peso 65 kg/m2. La densidad del acero estructural es 7850 kg/m3. Se conoce que la presión del viento sobre la pantalla es de 30 kg/m2 actuando de forma perpendicular sobre esta. Se pide determinar el ancho mínimo B para que el esfuerzo sobre el terreno debido a las cargas actuantes no sea mayor a 5 ton/m2.Considere una distribución constante de presiones. Haga un esbozo de la presión del suelo sobre la cimentación e indique la longitud apoyada sobre el terreno. Consideré que el peso de la pantalla led se aplica en el centroide del perfil tubular.

A2-m rigid tank initially contains saturated water vapor at 100 kpa. the tank is connected to a supply line through a valve. steam is flowing in the supply line at 600 kpa and 300 c. the valve is opened, and steam is allowed to enter the tank until the pressure in the tank reaches the line pressure, at which point the valve is closed. a thermometer placed in the tank indicates that the temperature at the final state is 200°c. determine (a) the mass of steam that has entered the tank (b) the amount of heat transfer.
