An elastomeric bearing pad is used to support a bridge girder as shown. The bearing pad provides flexibility in the horizontal direction to accommodate thermal expansion and earthquake motions. The shear modulus of the bearing pad is G = 1.50 MPa. The beam must not displace horizontally more than 25 mm when a load of P = 45 kN is applied as shown. Determine the maximum thickness t that can be used for the bearing pad. Assume a = 300 mm and b = 420 mm. Answer: tmax = i mm

The following figure shows the critical position of a crane that supports 2.5 Tons of load by means of a chain. You are delegated the responsibility of building a crane with similar geometric characteristics and load capacity. The diagram of free body of the crane arm can be redrawn as follows. (check the attached image "fbd") Assuming that the crane arm will be made of steel with yield stress sigmaY =220 MPa and that you must consider a safety factor of F.S.=1.5, propose a profile from the following catalog for the manufacture of the crane arm. Ignore the effects of shear forces on this element. On the other hand, it is very important that you consider the effects of axial loads. Commercial profiles for arm construction.
