Calculating the cross sectional area of a beam made up of three rectangular pieces. #crosssec . Center of Gravity . Calculating the center of gravity. #cog . Moment of Inertia of a Beam . Calculating the moment of inertia of the beam. #inertia . Bending Moment of a Beam . Simply supported beam at both ends with a single point load acting on it. #moment . Deformation of a Beam . Simply supported beam at both ends with a single point load acting on it (shear deformations are neglectable in this example). #deform . Normal Stress of a Beam
