If you run slightly different, lower circumference, tires on the front vs the rear during the winter months the automatic engagement of the rear driveline will have the ability for rear torque biasing beyond 50/50. 40/60 or maybe even 30/70. Much safer, like the Acura SH-AWD system, wintertime operation.

Are there standard calculations for determining safety factors? I am primarily interested in screw connections to steel. I often see safety factors from 2.5:1, 3:1 to the standard 4:1. How can calculations be done to show allowable loads with a FS lower than 4:1 be acceptable - that is assuming the test data is such so that the SD could allow this be done.

I am designing hole covers for a construction site by spanning sawn lumber. Per OSHA 1926.502(i)(2): "All other covers shall be capable of supporting, without failure, at least twice the weight of employees, equipment, and materials that may be imposed on the cover at any one time". I cannot find anything in the NDS that deals with safety factors. I could always load test, but that seems...

Without looking it up , how do you define terms like 'Safe Working Load' vs. 'Working Load Limit' vs. 'Breaking Strength'? I don't want the Wikipedia or Z300 copy/paste answers, I want what's in your head right now. I want to know how well we've been educated by manufacturers and safety organizations. We see these terms in lots of places, often under the guise of synonyms used in ...

1. The problem statement, all variables and given/known data An 8” long, 2.5” diameter, solid bar of Class 40 cast iron is subjected to both a torque of 75,000 lbf-in and an axial compressive load of 165,000 lbf. If these two loads can increase at a constant ratio, calculate the safety factor. 2. Relevant equations x =F/A xy =Tr/J n f ...

I need to look over at the University of Missouri, Columbia here in town and see if the old ME Automotive Design class I took way back in the early '70's has a text book b/c back then the Prof. was writing his own! He showed us how to use computer cards to figure all this out, talk about slide rule/computer stone age back then. pdq67
