A -7.5% grade meets a 3% grade at a vertex whose elevation is 146.24 m. directly under an overpass bridge whose underside is at elevation 152. 74 m. and carries another road across the grades at right angles. a. What is the longest symmetrical parabolic curve that can be used to connect the two grades and at the same time provide at least 5 m clearance from the bridge at its centerline? b. If the underside of the bridge is level and is 12 m. wide, Find the actual clearance on the left edge of the bridge.

Structural components of framed construction

It is a rigid and stable framework of structures that consists of structural members like slabs, beams, and columns that can resist the deformation due to the self-weight and high external loads and transfer the applied loads safely to the substructure and consecutively to the ground. It is made of different materials, such as reinforced concrete, steel, and wood. In ancient days, load-bearing structures were used to build houses and houses were built using load-bearing walls.
