A typical steel roof truss joint consists of THREE struts connected to a horizontal tie beam by means of an 8 mm thick gusset plate. FIGURE 1 (below) shows the layout of the members.
Part A:
Parts B and D:
Part C: 100 × 100 × 10 rolled-steel angles bolted to the gusset plate using THREE equally spaced M16 bolts
60 × 60 × 8 rolled-steel angles welded to the gusset plate by means of 8 mm fillet welds
70 × 70 × 8 rolled-steel angles bolted to the gusset plate using TWO equally spaced M12 bolts
Draw, to scale 1:5, the complete detail of the connection. Include all labels and welding symbols.
Answer (2)
A device with a current of 15.0 A for 30 seconds allows approximately 2.81 x 10^21 electrons to flow through it. This is calculated by first finding the total charge using Q = I × t and then converting the charge into the number of electrons using the charge per electron. Thus, the total electron flow is significant and illustrates how current relates to charge transport in physics.
