Homework 91)Design a 3-bit synchronous counter using D flip-flops. The counter will count when the enable (EN) is zero and hold when enable is one. The counter has an output, Z, which is high when the count is 100.

Heat transfer by is the fastest mode of heat transfer that requires no intervening medium. a)-conduction b)-convection c)-radiation d)-conduction and convection

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.

Technician a says that in a worm gear steering system, most excessive steering free play is usually found in the gearbox. technician b says that in a rack-and-pinion steering system, excessive free play can be found in the bushings. who is correct?
