We will use both shearing and bearing analysis to determine thequantities of rivets needed to fasten BC and BE. We can determine twovalues then choose what will be more safe.■ For Member BC:■ Based on Shearing:VT ==■AvBased on Bearing:PAb70MPa =96000 N.n.

If weonly use 5 rivets, then the bearing stress will become 168.42 MPa. It willresult to failure since the allowable bearing stress is only 140 Mpa.■ For member BE: (Practice at Home)PacEXAMPLE:5.
