A stick, pole, or bundle of switches or twigs (such as a birch), used for personal defense or to administer corporal punishment by whipping.

An implement resembling and/or supplanting a rod (particularly a cane) that is used for corporal punishment, and metonymically called the rod, regardless of its actual shape and composition.

A stick used to measure distance, by using its established length or task-specific temporary marks along its length, or by dint of specific graduated marks.

(archaic) A unit of length equal to 1 pole, a perch, 4 chain, 2 yards, 2 feet, or exactly 5.0292 meters (these being all equivalent).

An implement held vertically and viewed through an optical surveying instrument such as a transit, used to measure distance in land surveying and construction layout; an engineer's rod, surveyor's rod, surveying rod, leveling rod, ranging rod. The modern (US) engineer's or surveyor's rod commonly is eight or ten feet long and often designed to extend higher. In former times a surveyor's rod often was a single wooden pole or composed of multiple sectioned and socketed pieces, and besides serving as a sighting target was used to measure distance on the ground horizontally, hence for convenience was of one rod or pole in length, that is, 2 yards.

(archaic) A unit of area equal to a square rod, 4 square yards or 160 acre.

A straight bar that unites moving parts of a machine, for holding parts together as a connecting rod or for transferring power as a driveshaft.

(anatomy) A rod cell: a rod-shaped cell in the eye that is sensitive to light.

(biology) Any of a number of long, slender microorganisms.

(chemistry) A stirring rod: a glass rod, typically about 6 inches to 1 foot long and 8 to 4 inch in diameter that can be used to stir liquids in flasks or beakers.

(slang) A pistol; a gun.

(slang) A hot rod, an automobile or other passenger motor vehicle modified to run faster and often with exterior cosmetic alterations, especially one based originally on a pre-1940s model or (currently) denoting any older vehicle thus modified.

(ufology) A rod-shaped object that appears in photographs or videos traveling at high speed, not seen by the person recording the event, often associated with extraterrestrial entities.

(mathematics) A Cuisenaire rod.

(rail transport) A coupling rod or connecting rod, which links the driving wheels of a steam locomotive, and some diesel shunters and early electric locomotives.

(construction) To reinforce concrete with metal rods.

(transitive) To furnish with rods, especially lightning rods.

(slang) To hot rod.

A straight and slender stick; a wand; hence, any slender bar, as of wood or metal (applied to various purposes).

A kind of sceptor, or badge of office; hence, figuratively, power; authority; tyranny; oppression.

A measure of length containing sixteen and a half feet; - called also perch, and pole.

A linear measure of 16.5 feet

A long thin implement made of metal or wood

Any rod-shaped bacterium

A square rod of land

Visual receptor cell sensitive to dim light

Yes, certain types of rods, especially those made from non-conductive materials like fiberglass, are used in electrical applications to provide structure without conducting electricity.

Dowels commonly range from 1/4 inch to 1 inch in diameter but can vary based on the application.

Steel and aluminum rods are commonly used in automotive applications for parts like pistons and suspension components.

Rods can be cut using a hacksaw, band saw, or even a cutting torch, depending on the material.

Yes, many rods can be bent using heat or mechanical force, depending on the material, to fit specific design requirements.

Dowels can provide stronger joints in woodworking because they distribute stress more evenly across the joint.

The size of the dowel should match the thickness of the materials being joined to ensure a tight and secure fit.

Rods used outdoors should be treated or selected based on their resistance to corrosion and weather conditions.

In crafts, dowels are used for everything from making models and toys to serving as frames for fabric crafts.

Safety goggles should be worn to protect eyes from flying debris, and gloves are recommended to handle sharp or hot materials.

Yes, rods can be found in a variety of finishes such as polished, matte, or coated to enhance their durability and appearance.

Dowels offer a clean, professional look by hiding the connection points and can enhance the durability of the furniture.

The main disadvantage is the need for precise alignment during installation, as a poorly placed dowel can weaken the joint.

Material choice for dowels and rods should consider environmental exposure such as moisture, temperature, and chemical exposure to ensure longevity and performance.

Wooden dowels are a renewable resource and can be used to reduce the visibility of metal fasteners, contributing to more sustainable construction practices.
