	In the Block and Tackle shown there appears to be 3 ropes on each side joining the two blocks together and so its '''[[Mechanical Advantage]]''' would be 6 - i.e. pulling down on the rope with a force of 100kg would enable a load of 600kg to be lifted ''(assuming there are no losses due to friction)''.

			=====Description=====

	A [https://en.wikipedia.org/wiki/Block_and_tackle '''Block and Tackle'''] comprises a number of pulleys grouped together in blocks or '''''‘sheaves’''''' such that one block is fixed and the other is made moveable by means of a single continuous rope, or similar, threaded around them. In this configuration, the load is shared between the number of ropes threaded between the two blocks.
