Hookes law of elasticity is an approximation that states that the extension of a spring is in direct proportion with the load applied to it. Many materials obey this law as long as the load does not exceed the materials elastic limit. Materials for which Hookes law is a useful approximation are known as linear-elastic or "Hookean" materials. Hookes law in simple terms says that strain is directly proportional to stress.
F= -kxx is the displacement of the springs end from its equilibrium position S.I unit is meters F is the restoring force exerted by the spring on that end S.I unit is N or kg.m/s2 k is a constant called the rate or spring constant S.I unit N/m or kg/s2The negative sign indicates that the force exerted by the spring is in direct opposition to the direction of displacement.
Hookes law is named after the 17th century British physicist Robert Hooke. He first stated this law in 1660 as a Latin anagram, whose solution he published in 1678 as Uttensio, sic vis, meaning, "As the extension, so the force".
What is the force required to stretch a spring whoseconstant value is 100 N/m by an amount of 0.50 m? Using the formula F=kx solve the question F=force(N) k=force constant(N/m) x=stretch or compression(m) F=-(100N/m)(0.50m) F=-50 N
When a 13.2-kg mass is placed on top of a vertical spring,the spring compresses 5.93 cm. Find the force constant of the spring. Using Hookes Law: F = -kx Derivation: -k= F/x F=force(N) k=force constant(N/m) x=stretch or compression(m) 5.93cmx1m/100cm -k = F/x =0.0593m = (13.2x9.8)(0.0593m) k = -2181 N/m
