Let's Destroy a Bed

The Bed Project meets again on Thursday night at 7:00 pm.  For a change of pace, we will destroy a bed.  We need to test the safety of the new design and find the failure points.  Always wanted to have a dog-pile and jump on a bed, but your momma wouldn't let you?  Now is your chance.

Here are the tests and pass/failure criteria per our resident engineer.

1. Static load test. (gradually apply 800lbs one body at a time)
• No sign of failure at 800lbs. Some creaking allowed to be audible

2. No load scoot test. (push and pull on carpet from different points on the bed with the bed un-loaded)
• No sign of failure unloaded. Some creaking allowed to be audible.

3. Loaded scoot test. (push and pull on carpet from different points on the bed with the bed loaded)
• Minor stress cracks allowed with 100lb load. Some cracking sounds expected.

4. Dynamic load test to failure (apply a bouncing load one jumping body at a time for 3 minutes each until failure)
• No sign of failure with 100lbs bouncing for 3 minutes. Some creaking allowed to be audible. Expect failure between 200 and 800lbs.
