Define Young’s Modulus. The Young’s Modulus of a material its ratio of tensile stress to tensile strain. It is a measure of a material’s stiffness. How is stress calculated? Stress = Force/Cross-Sectional Area How is strain calculated? Strain = Change in Length/Original Length What is the unit of stress? Pascals (Pa) or N⋅m⁻² What is the unit of strain? Strain doesn’t have a unit since it is a ratio of two lengths. What is the unit of Young’s Modulus? Pascals (Pa) or ...

ASBOG - Engineering Geology Exam Review Qs&As 100% Verified Strain - ANS-An alteration in the shape or volume of a soil related to stress. It is calculated as the ratio of the new shape compared to the original shape Effective Stress - ANS-The total amount of stress placed on a soil minus the pore-water pressure Normal Stress - ANS-The component of total stress that acts perpendicular to the plane. Shear stress - ANS-The component of total stress that acts parallel to any point in question...

AQA AS LEVEL PHYSICS Paper 2 2021. A student investigates stationary waves using microwaves. Figure 1 shows a metre ruler fixed to a bench. The student places a microwave transmitter T at one end of the ruler and a vertical metal reflector R at the other end. R is at a right angle to the ruler. Figure 1 The student places a microwave detector D approximately one-third of the distance from T to R. When T is switched off, the microammeter connected to D reads zero. When T is switched on, ...

A 0.20-kg mass is oscillating on a spring over a horizontal frictionless surface. When it is at a displacement of 2.3 cm for equilibrium it has a kinetic energy of 1.5 J and a spring potential energy of 2.3 J. What is the maximum speed of the mass during its oscillation? - ️️6.2 m/s The air in a tube open at both ends is sent into its fundamental resonance. One end of the tube is then closed and the air column is again set into its fundamental resonance. The resonant frequency ____ after th...

MATSE 259 Exam 1 PSU Questions and Answers | Latest Version | 2024/2025 | Graded A+ How does strain relate to deformation in materials? Strain is the measure of deformation representing the change in length relative to the original length. What is yield strength? Yield strength is the stress at which a material begins to deform plastically. Why is Young's modulus important in materials science? Young's modulus measures a material’s stiffness, or resistance to elastic d...
