Question

Question 1 (60 points) The beam shown in Figure has been stiffened by the addition of a steel column support. The steel beam is 1.91 m long, 0.06 m thick, and 0.5 m wide, and its mass is 55 kg. The mass m is 580 kg. Neglecting the mass of the beam and column, compute the spring constant k necessary to reduce the static deflection to one-third of its original value before the steel column having stiffness k, was added. Also find out the round cross section area of the steel column support. m E=200GPa L=50m

Step 1

The deflection \( \delta \) of a simply supported beam with a central load \( P \) is given by: \[ \delta = \frac{PL^3}{48EI} \] where: - \( P = mg = 580 \, \text{kg} \times 9.81 \, \text{m/s}^2 \) - \( L = 1.91 \, \text{m} \) - \( E = 200 \, \text{GPa} = 200 Show more…

The beam shown in Figure has been stiffened by the addition of a steel column support. The steel beam is 1.91 m long, 0.06 m thick, and 0.5 m wide, and its mass is 55 kg. The mass m is 580 kg. Neglecting the mass of the beam and column, compute the spring constant k necessary to reduce the static deflection to one-third of its original value before the steel column, having stiffness k, was added. Also, find out the round cross-section area of the steel column support. E = 200 GPa. 50 m.
