You’re a highway safety engineer, and you’re asked to specify bolt sizes so the traffic signal shown in the Figure below won’t fall over. The figure indicates the masses and positions of the structure’s various parts. The structure is mounted with two bolts, located symmetrically about the vertical member’s centerline, as shown. What tension force must the left-hand bolt be capable of withst
