A horizontal beam AD with cross-section of 3800 mm² is supported by a wire at C and carries a load of 25kN at a point .8m from D. The wire has a cross-section of 1200mm². The beam AD is made of two sections AB and BD which are connected with a bolt. a) If the allowable shear stress in the bolt is 90mMPa, what is the minimum diameter of the bolt? b) If the allowable bearing stress in the bolt is 152 MPa, what is the minimum diameter of the bolt at C? B 20° 1.8m .@m 1-2m²
