4 The diagram shows one of four connectors used to attach a carriage to a fairground ride. Each connector contains a tie bar that supports an equal amount of load. Circular Pin F Diagram not to scale The carriage has a mass of 330 kg including two passengers. (a) Calculate the load F in one of the tie bars. Each tie bar has an original length of 370mm. When the load of carriage is applied, each tie bar extends by 3x10 mm. (b) Calculate the direct strain in one tie bar. State your answer to 3 significant figures (3 SF). The circular pin has a radius of 5x109 m. (c) Calculate the shear stress in the circular pin. (d) Explain how the modulus of rigidity (G) of the material used for the circular pinaffects its performance under loading.
