What can you accomplish with the Whip on Whip which you cannot accomplish with the Running Tackle? 18. If you are going to use a horse to move a load requiring a force of 800 pounds and have available plenty of rope which willstand 300 poimds, will you use the Whip on Whip, theRunning Tackle, or the Gun Tackle? Which will you useif the resistance is 500 pounds? 200 pounds? 19. It requires a force of 1,000 pounds to drag a gun 60 feet

It requires a force of 1,000 pounds to drag a gun 60 feet to the base of a high wall in which there is a stay bolt con-veniently located. There is available 75 feet of heavy ropecapable of standing a load of 1,500 pounds and 60 feet ofrope which will stand 600 pounds. Sketch the rigging youwould use for the job. Is this the only rigging which couldbe used advantageously? BLOCKS AND TACKLE 39 20. The men represented in Figure 5 are each exerting a force of50 pounds. Neglect friction and find: (a) The force which the snub must stand. (b) Th
