Newton /m2

It is named after Isaac Newton in recognition of his work on classical mechanicsspecifically his second law of motion, newton /m2.

One newton-metre is equal to the torque resulting from a force of one newton applied perpendicularly to the end of a moment arm that is one metre long. The unit is also used less commonly as a unit of work , or energy , in which case it is equivalent to the more common and standard SI unit of energy, the joule. This usage is generally discouraged, [3] since it can lead to confusion as to whether a given quantity expressed in newton-metres is a torque or a quantity of energy. Newton-metres and joules are dimensionally equivalent in the sense that they have the same expression in SI base units ,. Contents move to sidebar hide.

Newton per square meter is a metric measurement unit of pressure which serves as the base SI unit of pressure. The unit has a special name, the Pascal , after French mathematician, physicist and philosopher Blaise Pascal.

It is also used to quantify internal pressure , stress , Young's modulus , and ultimate tensile strength. The unit of measurement called standard atmosphere atm is defined as , Pa. Reports in the United States typically use inches of mercury [3] or millibars hectopascals. The unit is named after Blaise Pascal , noted for his contributions to hydrodynamics and hydrostatics, and experiments with a barometer. The pascal can be expressed using SI derived units , or alternatively solely SI base units , as:. One pascal is the pressure exerted by a force of magnitude one newton perpendicularly upon an area of one square metre. The unit of measurement called an atmosphere or a standard atmosphere atm is Pa The pascal Pa or kilopascal kPa as a unit of pressure measurement is widely used throughout the world and has largely replaced the pounds per square inch psi unit, except in some countries that still use the imperial measurement system or the US customary system , including the United States. Geophysicists use the gigapascal GPa in measuring or calculating tectonic stresses and pressures within the Earth. Medical elastography measures tissue stiffness non-invasively with ultrasound or magnetic resonance imaging , and often displays the Young's modulus or shear modulus of tissue in kilopascals.
