Consider a bridge represented as a simply supported uniform beam shown below. The effect of an operating equipment at the middle of the bridge is represented by a concentrated sinusoidal force F of magnitude F o = 1000 N, and frequency ϖ o = 2 rad/sec. Its material and geometric properties are (Note : these are team specific): Cross Sectional Area,A (m 2 ) Length ,L (m) Inertia, I (m 4 ) Modulus of Elasticity, E (N/m 2 ) Density, ρ (kg/m 3 ) A- Team 5 30 20 1.0 × 10 6 1.0 10 4 B- Team 7.5 30 30 1.0 10 6 1.0 10 4 C- Team 5 30 20 2.0 10 6 2.0 10 4 D- Team 7.5 30 30 2.0 10 6 2.0 10 4 E- G- Team 5 30 20 3.0 10 6 3.0 10 4
