1. Numerous small flotation devices are attached to the cable, and the difference between buoyancy and weight results in a net upward force of 30 newtons per meter of cable length. Determine the force T which must be applied to cause the cable configuration shown.
2. A series of spherical floats are equally spaced and securely fastened to a flexible cable of length 20 m. Ends A and B are anchored 16 m apart to the bot- tom of a fresh-water lake at a depth of 8 m. The floats and cable have a combined weight of 100 N per meter of cable length, and the buoyancy of the water produces an upward force of 560 N per meter of cable length. Calculate the depth h below the surface to the top of the line of floats. Also find the angle e made by the line of floats with the horizontal at A.
two forces f1 and f2 with magnitudes 40 and 55 newtons respectively act on an object at the origin. the angle f1 makes

Water is the working fluid in a regenerative Rankine cycle. Steam exits the first-stage turbine at 8 bar and its quality is 95%. 20% of that steam is extracted and diverted to an open feed water heater operating at 8 bar.
If the pipe is to be insulated with glass wool insulation (k=.05 W/m C) in order to decrease the temperature rise of water to .25 degrees C, determine the required thickness of the insulation.
