A steel supports a 160 lbm mass and results in an created in the rod. The rod. The rod has a length of 25" and a diamater of 0.35 and the young's modulus of the rod is E = 29.7 times 1.06 psi. Find the change in length of the rod? An electrical coil is made by winding copper wire around a core. What is the resistance of 50,00 turns of a 16-gague wire at an average radius of 2.0"? The 16-gauge wire has 0.075" diameter. Compare the resistance of a volume of 3 pi times 10 5 m3 of alumimum wire having a diameter of 5 mm, with the same volume of alumimum formed into 1 mm diameter wire. The ressistivity of aluminum is 2.76 times 108 Ohm m. A conductor made of nickle has a rectangular cross section 5 times 2 mm and is 7 m long. The resistivity of nickel is 6.78 times 10-8 Ohm m. Determine the total resistance of this conductor? Find the diameter of 6-m-long copper wire that has a circular cross section that yields the same total resistance?

Explanation / Answer

solution 1)

The load supported by the rod: F = 711.7154 Newton

Length of the rod: L = 635 mm

Diameter of the rod: D = 8.8900 mm
