2. Block and tackle - Wikipedia

   en.wikipedia.org/wiki/Block_and_tackle

   Consider the set of pulleys that form the moving block and the parts of the rope that support this block. If there are n of these parts of the rope supporting the load F B, then a force balance on the moving block shows that the tension in each of the parts of the rope must be F B /n. This means the input force on the rope is F A =F B /n.

   The cutting blades of a small electric chipper. The blades can be removed, by loosening the bolt in the center, to facilitate sharpening or for replacement. Much larger machines for wood processing exist. "Whole-tree chippers" and "recyclers", which can typically handle material diameters of 60–180 cm (2–6 ft), may employ drums, disks, or a ...

   Craftsman No. 5 jack plane A hand plane in use. A hand plane is a tool for shaping wood using muscle power to force the cutting blade over the wood surface. Some rotary power planers are motorized power tools used for the same types of larger tasks, but are unsuitable for fine-scale planing, where a miniature hand plane is used.

5. Pulley - Wikipedia

   A sheave or pulley wheel is a pulley using an axle supported by a frame or shell (block) to guide a cable or exert force. A pulley may have a groove or grooves between flanges around its circumference to locate the cable or belt. The drive element of a pulley system can be a rope, cable, belt, or chain.

6. Brace (tool) - Wikipedia

   en.wikipedia.org/wiki/Brace_(tool)

   A brace is a hand tool used with a bit (drill bit or auger) to drill holes, usually in wood. Pressure is applied to the top while the handle is rotated. If the bit's lead and cutting spurs are both in good working order, the user should not have to apply any pressure other than for balance: the lead will pull the bit through the wood.
