Chapter 10, Problem 34P

Under static loading by a weight of mass m, a rod of length L and axial rigidity AE deforms by an amount

δ = m g L A E , where g is the acceleration due to gravity. However, if the mass is applied suddenly (dynamic loading), vibration of the mass will ensue. If the mass m is initially at rest, the deflection x ( t ) satisfies the following second-order differential equation and initial conditions:

m x ¨ ( t ) + A E L x ( t ) = m g , x ( 0 ) = 0 , x ˙ ( 0 ) = 0. (a) Determine the transient solution, x t r a n ( t ) .

(b) Determine the steady-state solution, x s s ( t ) .

(e) Determine the total solution for x ( t ) , subject to the given initial conditions.

(d) Calculate the maximum value of the deflection x ( t ) .How does your result compare to the static deflection δ ?
