Elasticity Flashcards
1
Q
What is an equation for T(l) of a spring
A
λl/l0 where lambda is the elastic modulus and l0 is the unstretched length
2
Q
What is the equation for SHM
A
y ̈ + ω^2y = 0,
where λ/(ml0)
which has general solution
y = A sin ωt + B cos ωt.
hence x = x=l0+mgl0/lambda +Asinωt+Bcosωt.
