2 cards from this section. Quick, good the night before a test.
Define Hooke's Law in your own words.
Consider the relationship between force and deformation.
What does the modulus of elasticity represent?
Think about how hard or soft a material feels.
What is Hooke's Law?
Think about how force and deformation are related.
True or false: Hooke's Law applies to all materials regardless of strain.
Consider materials like rubber that behave differently.
A steel rod has a cross-sectional area of 2 cm² and is subjected to a force of 10,000 N. Calculate the stress and determine if it stays within its elastic limit if the yield strength is 250 MPa.
Convert area to square meters first for correct units.
A spring with a spring constant of 500 N/m is compressed 0.2 m. What is the force exerted by the spring?
Use Hooke's Law: F = kx, where k is your spring constant.
