Answer :
Final answer:
The largest load that can be safely supported in the wooden splice can be determined by calculating the tensile stress in the splice due to the load and comparing it to the maximum allowable tensile stress. The correct values for the largest load and shearing stress are in Option a) Load: 150 psi, Shearing stress: 30 psi.
Explanation:
The largest load that can be safely supported in the wooden splice can be determined by calculating the tensile stress in the splice due to the load and comparing it to the maximum allowable tensile stress. In this case, the maximum allowable tensile stress is given as 75 psi. To find the largest load, we need to find the tensile stress in the splice. Tensile stress is given by the formula:
Tensile Stress = Force/Area
The force is the load applied to the splice, and the area is the cross-sectional area of the splice.
To determine the shearing stress in the splice, we can use the same formula:
Shearing Stress = Force/Area
where the force is the load applied to the splice and the area is the cross-sectional area of the splice.
By substituting the respective values given in the options, we can determine the correct values for the largest load and shearing stress.
Answer: Option a) Load: 150 psi, Shearing stress: 30 psi
