DESCRIPTION
asdTRANSCRIPT
WORKOUT NO. 1Determine the axial forces of the indicated members of the different truss and indicate whether they are in tension or compression. Determine also the number of rivets necessary to connect them in a 9 mm gusset plate. The allowable shearing stress is 85 MPa and allowable bearing stress is 110 MPa. Tabulate the final answers in the table below.
