Initial force depending ontemperature

as before thepressure and force at other temperatures can be calculated as follows: Formula The temperature of the nitrogen gas affects the pressure in, and the force of, the gas spring. The forces given in the catalogue are based on a temperature of 20°C. Using the same basic Formula p p 1 T

0 = As the force is proportional to the pressure, it can alsobe written as: Formula F
1 = F

Example IV A gas spring with a initial force of 15000 N at 20°C isused in such a way that the gas spring temperature is increased to 60°C. What initial force will the spring have at 60°C?Solution using Formula F
1 = F

= 15 000 NT
1 = 273 + 60°C = 333°KT
= 273 + 20°C = 293°KF
1 = 15 000 • 333 = 17 000 N 293
