If a tensile force of 200 kN is being applied to member ABC, shown below, determine: a. The normal stress being developed in member AB b. The shear stress developed in the bolts at joint B c. The size of the nut that should be used at point A in order to bear the applied stress with a saftey factor of 4 if the maximum allowable stress for the steel used is 400 MPa. Assume the "nut" is cylindrical and its inner diameter is the same at the outer diameter of member AB. d 7 mm 40 mm 00 F-200 KN 30 mm
