The truss is supported by a pin at joint A and a horizontal link at joint B. The weights of members are negligible.

a) Determine if the truss is statically determinate or statically indeterminate. Show all work.
b) By inspection, identify the zero-force members in the truss.
c) Which zero force members can be removed without reducing the strength of the truss.

Fluids at rest possess no flow energy. a)- true b)- false

With increases in magnification, which of the following occur? a. the field of view decreases. b. the ambient illumination decreases. c. the larger parts can be measured. d. the eyepiece must be raised.

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.
