An engineer is designing a cylindrical steel pin that must fit into a bronze bushing for a high-precision application. The engineer has specified that the pin must have a limit size of 50.000 mm with a unilateral tolerance of -0.020 mm for a snug fit without the use of force. The bronze bushing will have a corresponding limit size of 50.030 mm with a unilateral tolerance of +0.020 mm. What type of fit is the engineer designing for? Calculate the maximum and minimum clearances between the pin and bushing. Discuss how temperature variations might affect the fit, assuming both components are made of materials with different thermal expansion coefficients.
