A cantilevered boom is part of an assembly machine and is made from an American Standard steel beam, S4X7.7. A tool with a weight of 500lb moves continuously from the end of the 60in beam to a point 10in from the support. A.) Draw a sketch of the variation of stress versus time, and compute the maximum stress, minimum stress, mean stress, alternating stress, and stress ratio, R. B.) Analyze the mean at the place where the maximum stress would occur at any time in the cycle.

Line joining liquid phase with liquid and solid phase mixture is known as: a) liquidus b) solidus c) tie line d) none of the mentioned
