A hanging wire made of an alloy of titanium with diameter 0.45cm is initially 10m long. When a 50kg mass is hung from it, the wire stretches an amount 1.63cm. A mole of titanium has a mass of 48g, and its density is 4.54g/cm. Based on these experimental measurements, what is Young's modulus for this alloy of titanium? Y=53 108Nim2

Consider a square-faced beam supporting a section of a building. a)  Before installation, the length of the beam is found to be l0 = 15.02 m (figure a). After installation and construction, the length is remeasured and found to be l = 14.98 m (figure b). Determine Young's Modulus Y in N/m2 for the beam if it supports a mass m = 35000 kg and has a side length d = 1.9 m.  b) Suppose that after the beam is installed it needs to be repaired. The weight it supports is removed and replaced with a new mass m2 (figure c). After the new mass is supported, the side length is remeasured and found to be larger with a difference of Δd. Assuming that this side length deformation is uniform and small, write an expression for determining Poisson's ratio v for this beam if its Young's modulus Y is known.

A 2.7-m-long, 1.0-mm-diameter steel string is pulled by a 3.9 × 103 N tension force. By how much is the string stretched, in mm? The Young's modulus for steel is 20 × 1010 N/m2. Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.

A 2m long, 1mm diameter wire is suspended from the ceiling. Hanging a 4.5kg mass from the wire streches the wire's length by 1mm. What is the Young's modulus for this wire? I just need teh answer please.

A hanging wire made of an alloy of aluminum with diameter 0.05 cm is initially 3.0 m long. When a 7 kg mass is hung from it, the wire stretches an amount 1.69 cm. A mole of aluminum has a mass of 27 grams, and its density is 2.7 g/cm3. Based on these experimental measurements, what is Young's modulus for this alloy of aluminum? Y= ____________N/m^2. As you've done before, from the mass of one mole and the density you can find the length of the interatomic bond (diameter of one atom). This is 2.55  10-10 m for aluminum. As shown in the textbook, the micro quantity ks,i (the stiffness of one interatomic bond) can be related to the macro property Y: ks,i = _______N/m

Suppose a piano tuner stretches a steel piano wire 5.5 mm. The wire was originally 0.825 mm in diameter, 1.27 m long, and has a Young's modulus of 2.10 × 1011 N/m2. l0 = 1.27 ml = 5.5 mmd = 0.825 mm Calculate the force a piano tuner applies to stretch the steel piano wire in Newtons. F =

Some claim that mountain climbers suffer from headaches due not only to a lack of oxygen in the brain, but also to the expansion of the brain in the cranium. Find the fractional change of the brain's volume due to a reduction in pressure from (1.48x10^2) kPa at sea level to 27.0 kPa high in the Himalayas. The bulk modulus is 2.10 GPa. Give your answer with three significant figures. Note: Your answer is assumed to be reduced to the highest power possible. Your Answer: x10 Answer
