Problem I. In a high-rise building construction, a boom is being used to efficiently transport materials from the ground to a certain level in the building. Shown below is a figure of the boom supporting the load 'P.' Note: P = 135kN -100 mm -87.5 mm 2P 12.5 mm dia 10 m -10 m At the right is the support detail at B. a) What is the normal stress (in MPa) the boom is subjected to if its cross sectional area is 1174 mm2 ? b) Calculate the shear stress in the pin (in MPa). c) If the allowable stress in the steel cable AC is 170 MPa, what should be size (diameter, in mm) of the cable to sufficiently withstand the force it is subjected to?
