4 cards from this section. Quick, good the night before a test.
Define Young's modulus.
What does it mean when we talk about material stiffness?
What are the units of stress?
Think about forces acting over areas.
What is Young's modulus?
Focus on the ratio aspect when recalling its definition.
True or False: Materials with a higher Young's modulus are generally more elastic.
Think about what elasticity specifically means.
A material has a Young's modulus of 70 GPa and is used as a beam in construction. If a load of 5000 N is applied and it deforms by 2 mm, calculate the length of the beam.
Use the Young's modulus formula to relate all knowns and unknowns effectively.
An aluminum wire has a diameter of 2 mm and a length of 1 m. If it is stretched by 100 N, determine the elongation. (Young's modulus for aluminum is 70 GPa.)
Calculate area first, then substitute into the equation for elongation.
