The diagram shows view of a suspension bridge.The road is supported by cylindrical steel rods attached to the suspension cables.There are 2 identical cables and sets of rods on each side of the roadway. Each pair of rods effectively supports 5m of road which has a mas per unit length of 2 x 103 kg/m.The longest rods are 55m long and have a cross-sectional area of 5 x 10-3 m2. young’s modulus for steel 2 x 1011 Pa Assuming that the limit of proportionality is not exceeded, calculate: The tension in each rod The tensile stress in the longest rods The tensile strain in the longest rods

Drainage of Pavements

Pavement Drainage holds ample significance, as it prevents the accumulation of water or any liquid on the surface of pavements and ensures proper drainage system. With proper design and gradual slopes provided, the water gets easily removed from the surface into the drains, which are essential during heavy rains and unusual weather conditions keeping it less prone to accidents and increasing the durability of the pavement structure.
