The pole in the figure below is at a 90° bend in a power line and is therefore subjected to more shear force than ones in straight parts of the line. The tension in each line is 4.60 x 10" N, at the angles shown The pole is 15.0 m tall, has a 16.0 cm diameter and can be considered to have 5.0 X10 N/m? the strength of hardwood. Assume Young's modulus to be 7.5 X10 N/m and the shear...

Two square wires are composed differently, see the figure of their cross-sections. Wire 1 is a square wire of material A but with a circular center of material C. The diameter of the circular inside is equal to the length of side of the square. The second square wire has the same cross-sectional area as the first but is entirely comprised of material A. Both wires are the same length and setup to have the same temperature difference maintained between...

Two steel wires are connected together, end to end, and attached to a wall as shown below. The two wires have the same length and elastic modulus, but the ratio of the radius of the first wire to the radius of the second wire is 5 : 2. As the wires are initially the same length, the midpoint of the combination coincides with the connection point. An applied force then stretches the combination by 2.650 mm while the two wires...
