1. You should not "post" so many duplicates of a question and then require admin to remove them.

2. About your question about removing the fence or other posts. The wording indicate a school task or project. You are actually required to do that yourselves.

Could you advise

The type of truck - does it have a winch or hoist mechanism. What is the relative height, H(m) of the truck lifting point to the post height(m) and buried depth(m) of the post?

What is the breaking strain of the strong rope you have available and what length ?

What are the lengths and sizes of the timber you have available and what is its strength?

jgrech,

Please refrain from posting duplicate threads. They will be removed by CR4 Admin. Also, if you are not getting an answer right away, please be patient.

CR4 is not a homework help site. If you are looking for help with your homework, you'd do well to listen to those who have already commented on your threads. The best thing you can do for yourself is to do your own homework. That's how you'll learn what your instructor wants you to know.

C'mon guys maybe he really does have some fence posts to remove from a site and doesn't know how to do it.

In reality you cut the posts off at ground level and put them in the back of the truck.

But let's pretend that they are antique posts and you don't want to destroy them. In which case you would dig them out with an escavator and carefully brush them off with brushes and seal them in hermatically sealed bags.

Because as anyone will tell you it's a considerable health and safety risk to try and yank them out of the ground because you'll end up with an uncontrolled tension in the rope when it breaks free from the ground, which could end up striking and killing someone.
