2. unit of young modulus
Answer:
Young's modulus = stress/strain = (FL0)/A(Ln − L0). This is a specific form of Hooke's law of elasticity. The units of Young's modulus in the English system are pounds per square inch (psi), and in the metric system newtons per square metre (N/m2).

8. A nylon rope used by mountaineers elongates 1.10 m under the weight of a 65.0 kg climber. If the rope is 45.0 m in length and 7.0 mm in diameter, what is Young’s modulus for nylon?
Explanation:
To determine Young's modulus for nylon, you will need to use the formula for Young's modulus, which is:
Young's modulus = (stress) / (strain)
In this problem, the stress is the force acting on the rope due to the weight of the climber, and the strain is the elongation of the rope.
To find the stress, you need to first determine the weight of the climber in Newtons. To do this, you can use the formula for weight, which is:
weight = mass * acceleration due to gravity
The acceleration due to gravity on Earth is approximately 9.8 m/s^2. Therefore, the weight of the climber in Newtons is:
weight = 65.0 kg * 9.8 m/s^2 = 637 N
The rope has a cross-sectional area of approximately 0.000386 m^2, which you can calculate using the formula for the area of a circle:
area = pi * radius^2
where the radius is the radius of the rope, which you can find by dividing the diameter by 2.
Next, you can determine the stress by dividing the weight of the climber by the cross-sectional area of the rope:
stress = (weight) / (cross-sectional area)
= (637 N) / (0.000386 m^2)
= approximately 1.65 x 10^7 Pa
To find the strain, divide the elongation of the rope by its original length:
strain = (elongation) / (original length)
= (1.10 m) / (45.0 m)
= approximately 0.024
Now that you have both the stress and the strain, you can use the formula for Young's modulus to find the Young's modulus for nylon:
Young's modulus = (stress) / (strain)
= (1.65 x 10^7 Pa) / (0.024)
= approximately 6.9 x 10^8 Pa
This is the Young's modulus for nylon under the given conditions.
#Hopethishelps9. modulus and elasticity
Answer:
An elastic modulus is a quantity that measures an object or substance's resistance to being deformed elastically when a stress is applied to it. The elastic modulus of an object is defined as the slope of its stress–strain curve in the elastic deformation region: A stiffer material will have a higher elastic modulus.
10. 1. Find the speed of sound in a steelrod assuming that the Young'smodulus is 2.2x1010 N/m2 andthe density is 1,000 kg/m3.
Explanation:
Sound
Sound waves are longitudinal. Our ears can hear the range of frequencies from 20Hz to 20,000Hz. This range is called the audible range. Frequencies above this range is called Ultrasonic that cats and dogs can hear. Ultrasound has medical application. By sending ultra sound wave to internal parts of body and analyzing the reflected sound waves, it is possible to create the image of a desired part by some imaging conversion process. Very high frequency (109Hz) ultrasound generated by electronic stimulation of quartz crystals is used in acoustic microscopy for generating sharp images.
The motion of sound waves in a gas, such as air, depends on the gas pressure and density. When a person speaks, the vibrations of his or her vocal cords cause air molecules to vibrate as well. Vibrations, at their best, propagate in air on spheres that expand and contract repeatedly transmitting their energy to bigger and bigger spheres thereby transmitting the sound energy via longitudinal waves. The shape of transmission in its ideal case is spherical and the sound energy propagates isotropically throughout the medium. Isotropic means same properties in all directions. We know that this is ideal and if you are standing in front of a speaker you hear it louder than standing at other places around it at the same distance. This means that the sound propagation from a speaker is directional and therefore, anisotropic.
The mechanism is that when a sphere of molecules expands, it creates a slight increase in pressure, ΔP, outward while leaving a slight relative vacuum, -ΔP, inward (or behind). This ripple in pressure causes a ripple in density that gets transmitted layer by layer, and the result is the transmission of sound waves.
Speed of Sound
The same way speed of waves in a string depends on the square roots of tensile force in the string and its mass per unit length, the speed of sound waves in a fluid depends on the square roots of the bulk modulus, B, of the fluid as well as its mass density, ρ. The bulk modulus of elasticity of a fluid is a measure of how compressible that fluid is when under a certain pressure. B is defined as the ratio of -ΔP over (ΔV / V). This simply calculates the change in pressure as a result of a relative change in volume. The Metric unit of B is N/m2. We may mathematically write:
Example 1:
The bulk modulus of elasticity of air is 1.41x105 N/m2 and its mass density is 1.29kg/m3. Calculate the speed of sound waves in air.
Solution: Using the formula v = (B / ρ )0.5, we get: v = [1.41x105 / 1.29] m/s = 331 m/s. (Speed of sound in air at STP)
Hope You Find This Example Useful!

13. Quiz #1 A steel bar is clamped to two vertical supports at 18 degrees Celsius. The coefficient of linear expansion for Aluminum is 11x10-6/C and the Young's Modulus of Steel is 200 x 10⁹ N/m². (a) Calculate the thermal stress on the steel bar at -30 degrees Celsius. (b) Calculate the thermal strain. (c) Find the Modulus of Elasticity of Steel.
Answer:
(a) To calculate the thermal stress on the steel bar at -30 degrees Celsius, we can use the formula:
σ = EαΔT
where σ is the thermal stress, E is the Young's Modulus of Steel, α is the coefficient of linear expansion for Aluminum, and ΔT is the change in temperature.
Since the steel bar is clamped to the vertical supports, it is prevented from expanding or contracting freely. Therefore, any change in temperature will result in a thermal stress being developed in the bar.
Using the given values, we have:
ΔT = (-30°C) - (18°C) = -48°C
σ = (200 x 10^9 N/m²) x (11 x 10^-6 /°C) x (-48°C)
= -105.6 N/m²
Therefore, the thermal stress on the steel bar at -30 degrees Celsius is -105.6 N/m².
(b) To calculate the thermal strain, we can use the formula:
ε = αΔT
where ε is the thermal strain, α is the coefficient of linear expansion for Aluminum, and ΔT is the change in temperature.
Using the given values, we have:
ε = (11 x 10^-6 /°C) x (-48°C)
= -0.000528
Therefore, the thermal strain is -0.000528.
(c) To find the Modulus of Elasticity of Steel, we can rearrange the formula for thermal stress:
E = σ/αΔT
Using the values we calculated earlier, we have:
E = (-105.6 N/m²)/(11 x 10^-6 /°C x -48°C)
= 180 x 10^9 N/m²
Therefore, the Modulus of Elasticity of Steel is 180 x 10^9 N/m².

The acceleration due to gravity on Earth is approximately 9.8 m/s^2. Therefore, the weight of the climber in Newtons is:
weight = 65.0 kg * 9.8 m/s^2 = 637 N
The rope has a cross-sectional area of approximately 0.000386 m^2, which you can calculate using the formula for the area of a circle:
area = pi * radius^2
where the radius is the radius of the rope, which you can find by dividing the diameter by 2.
Next, you can determine the stress by dividing the weight of the climber by the cross-sectional area of the rope:
stress = (weight) / (cross-sectional area)
= (637 N) / (0.000386 m^2)
= approximately 1.65 x 10^7 Pa
To find the strain, divide the elongation of the rope by its original length:
strain = (elongation) / (original length)
= (1.10 m) / (45.0 m)
= approximately 0.024
Now that you have both the stress and the strain, you can use the formula for Young's modulus to find the Young's modulus for nylon:
Young's modulus = (stress) / (strain)
= (1.65 x 10^7 Pa) / (0.024)
= approximately 6.9 x 10^8 Pa
This is the Young's modulus for nylon under the given conditions.
