Problem 2: The beam AB is supported by a pin at A and an axial link BC, which contains pins at ends B and C. Two concentrated forces of magnitude P are applied at the locations shown. Link BC has a cross sectional area of 250 mm² and can withstand a maximum normal stress of 120 MPa. Pin B has a diameter of 20 mm, is subjected to double shear, and can withstand a maximum shear stress of 60 MPa. A minimum safety factor of 3 is specified for the entire structure. C 30° B A-2m- -2 m- -2 m- Determine the maximum force P that can be applied, to satisfy all conditions. Draw complete and correct FBD(s) that match the equations used to solve this problem.
