A mountain bike manufacturer is considering a new product line that will include handlebarextenders applied to the ends of the handlebars, as shown below. To validate this design change,you have been tasked with analysing the structure. You have produced an idealised structure, shownbelow, where you consider half the length of the handlebars with a fixed boundary condition (A)applied to the plane of symmetry. You have estimated that the maximum load that a rider can applyto one handlebar extension is 75 Newtons that acts 100 mm from the centreline of the handlebars.The handlebars have a circular cross-section with an outer diameter of 32 mm and a wall thicknessof 3.25 mm. P1 is the critical point. If the maximum permissible tensile stress is 150 MPa and themaximum permissible in-plane shear stress is 55 MPa, what is the largest load, P, that can beapplied by the rider? Justify your answer.
