) The original design of the Menai Straits Bridge included four parallel wrought iron chain-links functioning as cables (two on each side of the deck), each with an equivalent cross-sectional area of 65 sq. in. How much horizontal tension force is carried by each individual chain-link cable, and what is the corresponding tension stress? If the breaking stress of the material is 25,000 psi (lb/ in2), what safety factor did Thomas Telford use?

The y form of iron is known as: a) ferrite b) cementite c) perlite d) austenite

The flow rate of air through a through a pipe is 0.02 m5/s. a pitot static tube is placed in the flow. the radius of the pitot static tube is 1 mm. assuming the flow to be steady and the air to be at 300k, calculate the difference in total and static pressure if the diameter of the pipe is: (a) d 0.1 m d 0.05 m (c) d 0.01 m

Liquid flows at steady state at a rate of 2 lb/'s through a pump, which operates to raise the elevation of the liquid 100 ft from control volume inlet to exit. the liquid specific enthalpy at the inlet is 40.09 btu/lb and at the exit is 40.94 btub. the pump requires 3 btu/s of power to operate. if kinetic energy effects are negligible and gravitational acceleration is 32.174 tt/s, the heat transfer rate associated with this steady state process is most closely 1)-2,02 btu/s from the liquid to the surroundings 2)-3.98 btu/s from the surroundings to the liquid. 3)-4.96 btu/s from the surroundings to the liquid. 4)-1.04 btu/s from the liquid to the surroundings.
