1 kg/cm2 = 10000 kgforce/m2
1 kgforce = 1 kg * 9.80665 m/s2 = 9.80665 Newtons
So 1 kg/cm2 = 98066.5 N/m2
1 Pascal is defined as 1 N/m2
So 1 kg per cm2 = 98066.5Pa
one mega pascle Equlas to ten kg/cm2 and vice versa
"When the gauge factor of a strain gauge is 2 stress is 1050 kgcm2 Y 2.1 106 kgcm2 and R is 100 ohms then the value of DR will be?"
Pascals
If you are thinking TPa, that is terapascals, or 1 trillion pascals. It is used where truly massive pressures exist. For tensile strength, no material has a strength measured that high. Most materials are measured in MPa, or 1 million pascals.
what is answer timber conversion
it depends on what your dealing with, room pressure is found with a barometer, to measure pressure in a flowing fluid, you can use a manometer. there are many variou ways to find pressure, but you must be specific on the circumstances
1 atm(atmospheric pressure)=101,325pa(pascals)
"When the gauge factor of a strain gauge is 2 stress is 1050 kgcm2 Y 2.1 106 kgcm2 and R is 100 ohms then the value of DR will be?"
1 psi = pounds per square inch equals 6894.757 pascals. that is arroud 6.89 kilopascals.Scroll down to related links and look at "Conversion of pressure or stress units".
305000 pascals
5 pascals (Pa) = 0.000005 megapascals (MPa)
"kilo" means a thousand. So 101300 pascals.
100000 pascals are 100000 Newtons per square meter. 100000 pascals are 100 kilopascals.
324 240 pascals
1 bar = 10^5 pascals (that's 10 to the 5th power, or 100,000 pascals)
105 ATM equals 10,639,125 Pascals
23800000 centipascals
4,632,000,000,000,000 picopascals
