This morning I saw a pickup carrying several sheets of plywood in the bed. They were strapped down. That got me thinking back to what my HS physics teacher told us, "Friction is your friend"--which for a classroom of mostly 15 year old boys sounds pretty funny.
So hypothetically speaking, if friction did not exist between those boards and the strap and we're dealing with normal Earth gravity at sea level, when the pickup accelerated from a stop, would the plywood slide out of the back of the truck?
I don't know the answer, just curious.
Happy Monday.
