ASK YOUR TEACHE A satellite similar to the Tethered Satellite in the figure below has a mass of 550 kg and is at the end of a 19.2 km long, 2.20 mm diameter cable with the tensile strength of steel. Tethered Satellite Bearth V Return path x through ionosphere (a) How much does the cable stretch (in m) if a 104 N force is exerted to pull the satellite in? (Assume the satellite and shuttle are at the same altitude above the Earth. Young's modulus for steel is 210 x 109 N/m2.) m (b) What is the effective force constant of the cable (in N/m)? N/m (c) How much energy (in J) is stored in it when stretched by the 104 N force?

5) Determine and select the steel required for both directions (bending and transverse) of a one- way solid slab that is 9 in. thick with a factored design moment of 16 k-ft for a 1 ft wide strip; f! = 4 ksi, fy = 50 ksi, d = 8.25 in. Limit the bars to #8 or smaller and observe the maximum spacing limits. (The moment capacity does not need to be determined.)
