Y12 Young Modulus Video

What does Young's Modulus measure in materials?

• Electrical conductivity

• Magnetic susceptibility

• Thermal expansion

• Elasticity or stiffness

Which equipment is not required for measuring Young's Modulus?

• Telescope

• Vernier scale

• Micrometer

• Pulley

What is the formula for calculating stress?

• Force / Area

• Mass x Gravity

• Change in length / Original length

• Area / Force

How is strain calculated in the context of Young's Modulus?

• Weight of the material

• Area of cross-section of the material

• Change in length / Original length

• Force applied on the material

What is the significance of using a caliper in the experiment?

• To measure the weight of the wire

• To measure the small change in length of the wire

• To calculate the force applied

• To hold the wire in place

Why is it recommended to take several measurements with varying weights?

• To ensure the wire does not break

• To calculate the average weight

• To increase the accuracy of Young's Modulus calculation

• To test the strength of the clamp

How is Young's Modulus determined from a stress-strain graph?

• By measuring the area under the curve

• Through the intercept with the y-axis

• From the gradient of the line

• By finding the highest point on the graph

In which fields is Young's Modulus still applied in modern engineering research?

• Software development and digital marketing

• Turbine systems and microcapsules

• Renewable energy and waste management

• Food industry and textile manufacturing

What does the application of Young's Modulus in turbine systems and microcapsules signify?

• It is only applicable in large-scale constructions

• Its versatility and importance in cutting-edge research

• It is outdated and no longer useful

• Its relevance is limited to mechanical engineering
