Impact Loading on a Beam
A weight W is dropped from a height h, striking at midspan a simply supported steel beam of length L. The beam is of rectangular cross section of width b and depth d (Figure 4.18). Calculate the maximum deflection and maximum stress for these two cases:
a. The beam is rigidly supported at each end.
b. The beam is supported at each end by springs.
Given: W = 100 N, h = 150 mm, L = 2 m, b = 30 mm, and d = 60 mm
Assumptions: Modulus of elasticity E = 200 GPa and spring rate k = 200 kN/m.
