The connection shown is bolted with an $A_{325}$ bolts with an allowable shearing stress of $207$MPa when threads are excluded from shear plane. $A_{36}$ steel is used with $F_y=248$MPa,$F_u=400$MPa. Assume bolt hole diameter to be $2mm$ bigger than bolt diameter. Diameter of bolt is $20mm.$ Use bearing type connection.

Calculate the ff:

a$.$ Tensile capacity of the connection if shearing stress governs

b$.$ Tensile capacity of the connection if bearing stress governs.

c$.$ Tensile capacity of the connection if tearing of plates governs
