Question

A 0.25" diameter A36 steel rivet connects two 1" wide by .25" thick 6061-T6 Al strips in a single lap shear joint. The shear strength of steel is 0.58oy. What is the maximum load before yielding? A. 2313 psi B. 1025 psi C. 3207 psi D. 1654 psi

Answer 1

Answer:

Option B

1025 psi

Explanation:

In a single shear, the shear area is $\frac {\pi d^{2}}{4}=\frac {\pi 0.25^{2}}{4}$

The shear strength=$0.58\sigma_y$ and in this case $\sigma_y=36 000 psi$

Shear strength=$\frac {Load}{Shear area}$ hence making load the subject then

Load=Shear area X Shear strength

Load=$\frac {\pi 0.25^{2}}{4} \times 0.58\times 36000\approx 1025 psi$
