Testing Roller Coasters WIth Fred

Posted by timothy on from the add-wilma-for-gender-parity dept.

An anonymous reader submits: "An AP article looks at the science of roller coaster testing. In general, a coaster must pass a "Fred" test, Fred being something analgous to a crash test dummy used in the automobile industry. Fred has a bunch of sensors in him that record data during the ride's operation and provide it all to engineers ensuring a ride's safety. Also discussed is pending regulation over G-Forces in New Joisey."

    The two things you're describing are the same thing. Any change in velocity -- velocity is a vector, with magnitude and direction -- is acceleration.

    Perhaps you meant to say "Jerk is what causes you to change the magnitude or direction of that acceleration."

    Funniest damn thing I've read in months. You can find the original article by Matthew Callan at Freezerbox.
