Which means if the equipment if design to has a high factor of safety, the cost to fabricate the equipment will increase and same to the weight too. But if the equipment is design with low cost and low weight, the factor of safety will be low too.
Factor of safety and probability of failure. 5. Obviously, it is desirable to include as many samples as possible in any set of observations. but, in geotechnical engineering, there are serious practical and financial limitations to the. amount of data which can be collected.
