Test Load
Test Load
(OP)
Hi,
DNV 2.7-3 (Portable Offshore Units) guideline states that the test load should be MGW X 2.5 x g, where MGW is the Maximum Gross Mass of the equipment, and g would be 9.81 m/s^2. Suppose the MGW is 5000 kgs, then the test load comes out to be 122,625 N. This is equal to 12,504 Kg. If you only multiply MGW X 2.5, it comes out to be 12,500 kgs. I am wondering the acceleration value of 1g, will only induce a difference of 4 kgs? Any comments or insight into this please?
Thanks in advance.

RE: Test Load
There is such thing as unit of Kilogram Foce (http://en.wikipedia.org/wiki/Kilogram-force) It is not commonly used but exists in physics.
@hungrydinosaur:
MGW [kg] = 5000
2.5 [-] = 2/5
g [m/s^2] = 9.81
Test Load = MGW*2.5*9.81 =122625 [N] =122.626 [kN]
units [Test Load] = [kg] * [-] * [m/s^2] = [N] (clear definition of Newton)
You can define load using mass but units have to be correct.
