Two wooden members are spliced as shown. If the maximum allowable tensile stress in the splice is 75 psi, determine the largest load that can be safely supported and the shearing stress in the splice.
a) Load: 150 psi, Shearing stress: 30 psi
b) Load: 100 psi, Shearing stress: 25 psi
c) Load: 200 psi, Shearing stress: 20 psi
d) Load: 120 psi, Shearing stress: 15 psi
