Extracted text: SITUATION 31 Consider the system above. A rubber is used to bond a solid steel shaft (Diameter = 130mm) to another steel pipe (Diameter=200mm), fixed on the ground. A simple lever is used to test the bond between the two caused by the rubber. Bar AC has a length of 3m, a pin at B is used as the fulcrum of the system. Pin at B has allowable shearing stress of 100 MPa, the rubber has modulus of elasticity of 4.2 MPa and Poisson's ratio of 0.42. Consider deformation on rubber only, and pin at B experiencing double shear. 2000 100. A D-lémm 1. Determine the maximum vertical displacement of the shaft to not exceed the working shearing stress of the pin at B. 2. Considering Pin at B will not collapse.
