Chapter 11, Problem 11.56(choose chapter or problem)
A block of weight W is dropped from a height h onto the horizontal beam AB and hits it at point D. (a) Show that the maximum deflection ym at point D can be expressed as
\(y_{m}=y_{s t}\left(1+\sqrt{1+\frac{2 h}{y_{s t}}}\right)\)
where \(y_{s t}\) represents the deflection at D caused by a static load W applied at that point and where the quantity in parenthesis is referred to as the impact factor. (b) Compute the impact factor for the beam of Prob. 11.52.
