A metal wire 1.3 mm in diameter and 2.5 m long hangs vertically with a 5.1-kg object suspended from it. Part A If the wire stretches 1.7 mm under the tension, what is the value of Young's modulus for the metal? Express your answer using two significant figures.
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.
A mineshaft has an elevator hung from a single steel-wire cable of diameter 2.5 cm. Young's modulus of the cable is 10×1010N/m2. When the cable is fully extended, the end of the cable is 600 m below the support. How much does the fully extended cable stretch when 1000 kg of ore is loaded into the elevator?
A mineshaft has an elevator hung from a single steel-wire cable of diameter 2.5 cm. Young's modulus of the cable is 10×1010N/m2. When the cable is fully extended, the end of the cable is 900 m below the support. How much does the fully extended cable stretch when 1200 kg of ore is loaded into the elevator?
A steel lift column in a service station is 3.0 meters long and. has an area of 0.2 m2. Young’s modulus for steel is 20 x 1010 N/m2. By how much does the column shrink when a 3000 kg load is on it? A)3.1 x 10-5 m B)2.25 x 10-7 m C)3.5 x 10-6 m D)2.2 x 10-6 m
A steel wire of length 1.6 m and diameter 0.80 mm is joined to an aluminum wire of identical dimensions to make a composite wire of length 3.2 m. Find the resulting change in length of this composite wire if an object with a mass of 5.00 kg is hung vertically from one of its ends. (Neglect any effect the masses of two wires have on the changes in their lengths.) mm
Find the minimum diameter of an l = 16.7 m long steel wire that will stretch no more than 9.53 mm when a mass of 361 kg is hung on the lower end. (Hint: The Young's modulus of steel is 200.0 GPa.)
