Determine the buckling load under two assumptions

Reference no: EM131152177

A set of four wood members are lashed together at several points along the length with the goal of creating a bar with a larger cross-section that is less susceptible to buckling. Each member is 8 ft long and has a square cross-section of width d = 0.875 in (so altogether the beam consisting of four members is 1.75 in. square). Using an elastic modulus of wood of 1.6(10⁶) psi, and treating the members as simply supported, determine the buckling load under two assumptions:

(a) the members are lashed together well enough that they function as a single solid beam and

(b) the members bend individually, each taking one quarter of the load.
