Q:

How do you bend a steel rod?

A:

A steel rod is bent by applying force to two or more points on the rod in opposition. The amount of force necessary and how the steel bends depend on several factors including strength and toughness.

There is no one kind of steel. As stated by SteelConstruction.info, steel is rated by five different categories. The first is strength, or the ability for the steel to keep its shape. The second is toughness, or the ability of the steel to bend rather than break or shatter when it is put under stress. The third is ductility, or the ability of the steel to be pushed together or pulled apart without cracking or failing. The fourth and fifth qualities, weldability and durability, do not impact how steel bends.

A steel rod with low strength and high toughness bends quite readily. A steel rod with high strength and low toughness resists being bent, but shatters and breaks off instead of bending when it does give way.

Steel is an alloy of metals combined under specific conditions. A steel's composition, smelting, forging and tempering affect all of the five characteristics mentioned. Characteristics for any given piece of steel are generally available from the manufacturing company.

    What is an equilibrant force?

    A:

    Equilibrant forces are those that act on a body at rest and counteract the force pushing or pulling the body in the opposite direction. Equilibrant forces establish equilibrium for an object and make the object motionless. Equilibrant forces act on virtually every object in the world that is not moving.

  • Q:

    What is the equation for force?

    A:

    The equation for determining the net force acting on an object is F = ma, or force equals mass times acceleration. Net force is measured in terms of acceleration, which means a change in velocity. If there is no change in velocity, the net force is considered to be zero.

  • Q:

    What is net force?

    A:

    A net force is the remaining force that produces any acceleration of an object when all opposing forces have been canceled out. Opposing forces decrease the effect of acceleration, lowering the net force of acceleration acting on an object.

    What is the force that always opposes motion?

    A:

    Friction always opposes motion between two surfaces, although it is not a fundamental force of the universe like gravity. The coefficient of friction is used to describe the ratio of friction between two bodies and the outside force pressing them together.
