To identify the conceptual properties of simple trusses. A truss is a structure composed of slender members that are connected at their ends. Planar trusses lie in a single plane and are often used to support roofs and bridges. In designing a truss's members and connections, three assumptions are made: All loadings are applied at the joints. The members are connected by smooth pins. All members in a truss are straight. Each member acts as a two-force member and the forces at the ends of the member must be directed along the member's axis. Because trusses consist of two-force members, each member is either in tension (being pulled apart) or in compression (being pushed together).

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.

To design a steam turbine to produce 12,000 hp power. a engineer comsiders using a steady state stean low st 1160fr and engineer considers using a steady state steam flow at 1160°r and 450 psia to drive this steam turbine. the exhaust of the steam is cooled by the lake (vacuum). heat losing to the surroundings is measured at a rate of 555.55 btu/s. (a) sketch the system with the given conditions. (b) neglecting kinetic and potential energy changes from inlet to exit, determine the volumetric flow rate of the steam at the inlet, (ft'/hr). must clearly show unit conversions at crtical terms.
