What is a halyard on a flagpole?
Flagpole halyard is rope, lanyard, wire-center halyard or stainless steel cable. These are the various ways to rig a flagpole. The halyard is what allows the flag to travel up and down the flagpole. An External Halyard Flagpole System places the rope on the outside of the flagpole.
How do you rig a flagpole halyard?
Basically, all you need to do is:
- pinch together the flagpole rope.
- push the loop through the eyelet of the flagpole clip.
- pull the halyard loop over the clip end of the flagpole clip.
- pull the halyard tight so that the clip sits snugly in place.
What is halyard rope?
In sailing, a halyard or halliard is a line (rope) that is used to hoist a ladder, sail, flag or yard. The term halyard comes from the phrase “to haul yards”. Halyards, like most other parts of the running rigging, were classically made of natural fibre like manila or hemp.
Is a scissor a lever?

Is a shovel a lever?
The shovel is a lever when it is used to lift soil out of the ground. The resistance load is the soil on the head of the shovel. In the case of a 2-handed shovel the hand closer to the head of the shovel is the fulcrum, and the hand on the handle exerts the effort force.
What kind of lever is a broom?
third class levers
With third class levers the effort is between the load and the fulcrum, for example in barbecue tongs. Other examples of third class levers are a broom, a fishing rod and a woomera.
Is light switch a lever?

How can a wheel and axle be thought of as a lever?
