Question 1: Figure below shows a wood beam supported on two springs and loaded in bending impact. Estimate the maximum stress and deflection in the beam, based on the assumption that the masses of the beam and spring can be neglected. 20 in. 100 lb 2 x 4 white pine E = 10 psi Mod. of rupture = 6 ksi 14 in. 100 lb/in. 100 lb/in. 4 iş in. x 3 in., 1 = bh3/12 = 6.46 in. , Z = Ilc = 3.56 in.3 40 in.
