1. A cable used to lift heavy materials can resist breaking even under a load of 1 meganewtons. The steel cable must support twice that load for safety purposes. By how much the steel cable will stretch if it carries 1 meganewtons of load? Assume 8.0 m initial length of the cable. 2. Ships and sailing vessels often carry lead ballast in various forms, such as bricks, to keep the ship properly oriented and upright in the water. Suppose a ship takes on cargo and the crew jettisons a total of 0.500 m3 of lead ballast into water 2 000 m deep. Seawater's density is equal to 1.025 g/cc while lead's bulk modulus equals to 42.0 GPa. Calculate the weight of water in a column with cross section of 1.00 m2. Find the change in the pressure at 2.0 km depth. Find the change in the volume of the lead at 2.0 km depth.

The maximum acceleration that the computer can withstand on impact with a hard surface is 4g. At the maximum acceptable impact acceleration, how much does the packaging compress upon impact? Give the answer in cm. What is the maximum height, h, in cm that the case can fall from without damaging the computer?
5.15. A small-parts assembly line involves the use of solvents requiring a high level of ventilation. To achieve removal of these toxic gases, a mean velocity of 8 ft/s must be maintained across the cross-section of a 12 ft high by 30 ft wide room. The toxicants are subsequently removed in a wet scrubber or filter, which causes a pressure drop of 30 lb/ft². Using a Cordier analysis, select the design parameters for a fan that will provide the required flow and pressure rise, while oper ating at or near 90% total efficiency, and that minimizes the diameter of the fan. Give dimensions and speed of the fan and describe the type of fan chosen.

The floor sits upon the minor length of the joist, and the joists are set at equal spacing to reach the desired floor stiffness.

4) One measure of the scale of a process is its throughputs of fuel or other input raw materials, e.g., lbs of coal per hour. Compare the coal throughputs for a small-scale experiment that uses 10 mg of coal in 6 seconds, and a single boiler in a large commercial-scale central-station electric generating plant. Assume: the commercial facility has a total output of 1,020 MW e supplied by three boilers of equal capacity; the boiler has a heat rate of (8,980 Btu th /hr)/(kW e ) based on fuel HHV, and fires coal with a gross heating value (i.e., HHV) of 14,000 Btu th /lb.
