DISCUSSION THREAD
Hints: Use the method of joints to determine the loads carried by the three members of the truss. Review the earlier section in Chapter 3 regarding the shear stress in pins due to direct shear.
Any questions? Ask (and answer) questions here.
The factor of safety equation uses yield stress not yield strain. Therefore, can we use the factor of safety equation in terms of strain? Because we do not have the value of E, we are not able to calculate stress from strain. Therefore, do we use the FS equation or just set strain to the yield strain?
Ignore my previous comment I was confused.
I am wondering if the pin is single shear or double shear. Thanks.
The figure shows it to be double-sided.
