Chapter 12, Problem 39SP
A horizontal rectangular platform is suspended by four identical wires, one at each of its corners. The wires are 3.0 m long and have a diameter of 2.0 mm. Young’s modulus for the material of the wires is 180 GPa. How far will the platform drop (due to elongation of the wires) if a 50-kg load is placed at the center of the platform?

- An aluminium (=2.7g/cm3) wire is suspended from the ceiling and hangs vertically. How long must the wire be before the stress at its upper end reaches the proportionality limit, which is 8.0107N/m2 ?arrow_forwardThe lintel of prestressed reinforced concrete in Figure P12.27 is 1.50 m long. The concrete encloses one steel reinforcing rod with cross-sectional area 1.50 cm2. The rod joins two strong end plates. The cross-sectional area of the concrete perpendicular to the rod is 50.0 cm2.
