Question

Two flat bars loaded in tension by force P are spliced using two rectangular splice plates and two 0.350 in. diameter bolts. Away from the connection, the bars have a width of b = 0.625 in. and a thickness of t = 0.15 in.  The bars are made of polyethylene having an ultimate tensile strength of 3200 psi and an ultimate bearing strength of 1500 psi. The bolts are made of nylon that has an ultimate shear strength of 4400 psi. Determine the allowable load P for this connection if a safety factor of 3.7 is required.  Consider tension and bearing in the bars and shear in the bolts.  Disregard friction between the plates.

 

Two flat bars loaded in tension by force Pare spliced using two rectangular splice plates and two 0.350 in. diameter bolts. Away from
the connection, the bars have a width of b = 0.625 in. and a thickness of t = 0.15 in. The bars are made of polyethylene having an
ultimate tensile strength of 3200 psi and an ultimate bearing strength of 1500 psi. The bolts are made of nylon that has an ultimate
shear strength of 4400 psi. Determine the allowable load P for this connection if a safety factor of 3.7 is required. Consider tension
and bearing in the bars and shear in the bolts. Disregard friction between the plates.
