The sum of all forces on object, part, and particle is zero. ZF =0 b. The internal shear in a bending member is the integral of the external loading and the internal moment is the integral of the shear. V = Jw-dx and M = SV-dx c. The force applied to an object is the product of its mass and acceleration. F= m-a d. The load effect caused by two or more loadings is equal to the sum of the load effects caused by each individual loading F(x1+x2) = F(x1) + F(x2) In 2-3…
Q.10
A bridge, as shown below, shall carry a distributed load of 280 kN/m2. For the given load andassuming Fy = 345 MPa: 1) Find the smallest W section that carries the applied shear load.2) Find the smallest W section that carries the applied moment.3) Design the beam by considering the shear, moment, as well as a deflection limit of L/240. The hot-rolled, i.e., prefabricated, W sections have limited sizes. Assume that the load has beenincreased dramatically, and we cannot use prefabricated W sections. In this case, what would beyour suggestion to have a beam that is able to carry the load? (Provide at least three suggestions.)
