Torque or Moment of Force - Online Converter
Torque or moment - the tendency of a force to rotate an object around an axis or a point - is defined asthe product of the force and the distance from the point or axis to the force vectorTorque can be expressed asT = F a (1)whereT = moment - or torque of the force (Nm, lbf ft)F = applied force (N, lbf)a = moment arm (m, ft)Example - Torque exerted by a WrenchA force of 250 N is acting at the end of a 30 cm long wrench. The torque exerted can be calculated asT = (250 N) (30 cm) (0.01 cm/m) = 75 Nm
The Law of Lever is a torque balance on a stationary object and can be expressed as
F1 / F2 = L2 / L1 (2)whereF = force (N, lbf)L = distance from the point (1 or 2) to the force vector (m, ft)(1) can be transformed to
F1 L1 = F2 L2 (2b)orT1 = T2 (2c)Example - LeverA person with a mass of
90 kg is standing on one side of a lever
2 m from the balance point. The force on the other side of lever
0.5 m from the balance point can be calculated by modifying (2) to
F2 = F1 L1 / L2 = (90 kg) (9.81 m/s2) (2 m) / (0.5 m) = 3531 N
Moment of force (also called torque or just moment) is the tendency of a force to twist or rotate an object. A moment is the product of the force and the moment arm. The moment arm is the perpendicular distance from the point of rotation, to the line of action of the force. The moment may be thought of as a measure of the tendency of the force to cause rotation about an imaginary axis through a point.In SI, the moment of force is measured in newton-meter (N·m). One newton meter is equal to the torque resulting from a one-newton force applied perpendicularly to a one-meter long moment arm. In CGS, the moment of force is measured in gram-force centimeter (gf·cm).Using the Moment of Force Converter ConverterThis online unit converter allows quick and accurate conversion between many units of measure, from one system to another. The Unit Conversion page provides a solution for engineers, translators, and for anyone whose activities require working with quantities measured in different units.
You can use this online converter to convert between several hundred units (including metric, British and American) in 76 categories, or several thousand pairs including acceleration, area, electrical, energy, force, length, light, mass, mass flow, density, specific volume, power, pressure, stress, temperature, time, torque, velocity, viscosity, volume and capacity, volume flow, and more.
Note: Integers (numbers without a decimal period or exponent notation) are considered accurate up to 15 digits and the maximum number of digits after the decimal point is 10.In this calculator, E notation is used to represent numbers that are too small or too large. E notation is an alternative format of the scientific notation a · 10x. For example: 1,103,000 = 1.103 · 106 = 1.103E+6. Here E (from exponent) represents “· 10^”, that is “times ten raised to the power of”. E-notation is commonly used in calculators and by scientists, mathematicians and engineers.In the list on the right, select the unit to convert from.Enter the value (for example, “20”) into the corresponding input box.The results of the conversion will immediately appear in all unit boxes.Find the unit to convert to in the list and read the calculated value.Alternatively, you can enter the value into any right input box, and the results of the conversion will be immediately recalculated.We work hard to ensure that the results presented by TranslatorsCafe.com converters and calculators are correct.
