![]() ![]() ![]() Concrete's modulus of elasticity is between 15-50 GPa (gigapascals), while steel tends to be around 200 GPa and above. The higher a material's modulus of elasticity, the more of a deflection can sustain enormous loads before it reaches its breaking point. The modulus of elasticity depends on the beam's material. We can define the stiffness of the beam by multiplying the beam's modulus of elasticity, E, by its moment of inertia, I. ![]() Calculate the fractional decrease in wire radius.Calculating beam deflection requires knowing the stiffness of the beam and the amount of force or load that would influence the bending of the beam.Calculate the tensile stress in the wire.Calculate the force needed to push the cork into the bottle.Calculate the displacement when force is applied on a cube.Calculate the energy stored in the wire.Determine the length of the cord when Young’s Modulus is given.Determine the ratio of e=increase in length of two wires of same material.Ratio of hydraulic stress to strain is?.Which substance has highest elasticity?.Calculate the stress relation between two extended wires.Calculate the elastic potential energy in the elongated wire.Calculate the force required to stretch the wire.Ratio of increase in length of steel and copper wires.Ratio of weights of steel and brass wires upon suspension.Choose the correct relation between the parameters of elesticity.Previous Year Questions on Beam Deflection Formula Important Topics From Chapter: Mechanical Properties of Solids The bulk modulus is relevant for solids, liquids and gases.The young’s modulus and shear modulus are relevant only for solids.Three elastic modules which are young’s modulus, shear modulus and bulk modulus are used to describe the elastic behaviour of objects as they respond to deforming forces that act on them.Young’s Modulus is the property of the material which does not depend on the external factors like force, moment etc. ![]()
