A mass of 50. kg is suspended from a steel wire of diameter 1.0 mm and length 11.2 m. How much will the wire stretch? (The Young's modulus for steel is 20 × 10^10 N/m^2) The answer is 34.9 mm Showing all work please explain how this answer came about.
1. A closely coiled helical spring made of 15 mm diameter steel wire has 15 coils of 110 mm mean diameter. The spring is subjected to an axial load of 180 N. Calculate the maximum shear stress induced in the spring. Assume modulus of rigidity is 78 GPa. 2. A solid circular bar ABC consists of two segments, as shown in the figure. One segment has diameter d1= 65 mm and length L1 = 1.54 m; the other segment has...
A hanging magnesium wire with diameter 2.4 mm (2.4 × 10-3 m) is initially 0.60 m long. When a 100 kg mass is hung from it, the wire stretches an amount 3.25 mm. A mole of magnesium has a mass of 24 grams, and its density is 1.74 g/cm3. Find the approximate value of the effective spring stiffness of the interatomic force.
A steel (density 7.86 x 103 kg/m3) wire of length 1.20 m and diameter 0.644 mm is subjected to a tension of 34.5 N. At one end of the wire is an oscillator harmonically oscillating one end of the wire at a frequency of 60 Hz, the other end of the wire runs over a pulley to a hanging mass that supplies the tension.What is the wavelength of the waves produced by the oscillator?
Find the minimum diameter of a copper wire 20 m long that will stretch no more than 14mm when a load of 400 kg is hung on the lower end. (Ycopper = 1.3 x 1011 N/m2)
Problem 3 The length of the 2 mm diameter steel wire CD has been adjusted so that with no load applied, a gap of 1.5 mm exists between the end B of the rigid beam ACB and a contact point E. Knowing that E= 200 GPa, determine the distance x where a 20 kg block should be placed on the beam in order to cause contact between B and E. 250 mm 20 kg B 1.5 mm 80 mm
A metal wire having a diameter of 1.1390 mm and a length of 514.1 mm is deformed elastically in tension with a force of 1,660 N. Given that the elastic modulus and Poisson's ratio of the metal are 115 GPa and 0.3410, respectively, determine the change in diameter of the specimen (in mm).
