There is no single diameter - there are steel rods of different diameters for different uses.
The number of steel rods in a ton will depend on the size and diameter of the rods. Typically, a ton of steel rods can range from around 540 to 650 rods, assuming they are standard size and weight.
depending on the diameter of the rod, generally there will be approx. 26 (+/- 1) welding rods per pound.
Depends on what you're checking. A piece of window glass works well for checking push rods for straightness. A machinists straight edge is good for checking heads and decks.
sansa is an instrument in which you pluck some (usually 16-27) thin metal rods sticking out of a wooden box. It is a traditional African instrument.
Azotobacter's cells are large rods, at least 2 microns in diameter

The number of 6013 welding rods in 1 kg depends on the length and diameter of the rods. Typically, a standard 6013 rod is 3.2 mm in diameter and about 350 mm long, weighing approximately 0.4 kg each. Therefore, you can expect to have around 2 to 2.5 rods per kilogram, depending on specific dimensions and manufacturing variations.
No the diameter of the crank journals are different.
The best curtain rods for blackout curtains are typically heavy-duty rods made of sturdy materials like steel or wrought iron. These rods are designed to support the weight of blackout curtains without bending or sagging, ensuring that the curtains can effectively block out light. Look for rods with a diameter of at least 1 inch for added strength and stability.
The weight of 5 rebar rods can vary depending on the diameter and length of the rebar. As a general estimate, a standard size #5 rebar (5/8-inch diameter) that is 20 feet long weighs around 15.41 pounds. Therefore, the weight of 5 such rebar rods would be approximately 77.05 pounds.
