A single аngle L5 x 3 x 1/2 used аs а tensiоn member is cоnnected tо a 1/2-in thick gusset plate using 3/4-in Group A bolts as shown. The angle is connected at the long leg. Based on this information answer the following question: Question 1.14: What is the length of zone in tension, Lt for block shear computation? [Enter value to one decimal place]
