PROBLEM: A simply supported beam is subjected to a harmonic load F(t)-Fo sin ณ at mid-span as a result of the operation of a mechanical system that rotates at a constant speed n rev/min. The beam is made from steel with an elasticity modulus E 29x103 ksi and specific weight 490 lb/ft3. The beam has a cross-sectional area A = 1.59 in, a moment of inertia 1 = 3.85 in, and an approximate viscous damping factor 0.05. The length between...

2) The beam shown is supported by steel member BC as shown. Due to the forked ends on the member, consider the supports at B and C to act as pins for x-x axis buckling and as fixed supports for y-y axis buckling. Member BC is made of A992 steel with a modulus of elasticity of 29,000 ksi and a yield strength of 50 ksi. a) Calculate the maximum allowable load, P, on the system (in kips) considering buckling and...
