Part A -80 mm- P 75 mm -40 mm 30 mm If the bolt head and the supporting bracket are made of the same material having a failure shear stress of Tfail = 150 MPa, determine the maximum allowable force P that can be applied to the bolt so that it does not pull through the support. Apply a factor of safety of F.S. = 2.5 against shear failure. Express your answer to three significant figures and include the appropriate units.

For a lap joint, determine the maximum safe load P which may be applied if the shearing stress in the rivets is limited to 60 MPa, the bearing stress in the plates to 110 MPa, and the average tensile stress in the plate to 140 MPa

FBD 3. Determine the required thickness of member BC and the diameter of the pins at A and B if the failure normal stress for member BC is Ofail = 30 ksi, and the failure shear stress for the pins is Tfail = 12 ksi. Use a safety factor of 1.2 to your design. Solution: 1.5 in. 60° 8 ft 5 kip/ft

An axial load is applied to the rectangular cross section bar which is welded at the 57 degree angle shown. If the weld material has a failure normal stress of 160 mPa and a failure shear stress of 90 mPa, determine the required thickness if a factor of safety of 2.3 is required. Also determine the required diameter of the bolts(to the nearest mm) if the plate is face bolted to the supports. The bolt material has a failure shear stress of 175 mPa.
