A question please in three parts, need the numbers for the first before I can asked the next.
A Machine lowers from rest, 100 pounds under control, at 2m/s, for 1000mm. Then immediately stops the weight, and lifts it back up at 2m/s.
At the transition from negative to positive, what impulse force in pounds, would be the maximum on the Machines components/parts, and for how long, until the normal acceleration forces that would be on the components/parts if it lifted the weight from rest.
Just in case I did not explain right. The force on the components/parts, lifting from rest would keep getting higher, let's go for every 10th of a second. Say from the lift at rest, the first 10th of a second would have at that vilocity ? 105 pounds of force needed to lift the weight at that vilocity, then the next 10th of a second it may need 110 pounds as the vilocity went up, and more and more force would be needed to keep the vilocity going up, until the decceleration. But what would be the impulse/force on/from the components/parts if the weight was lowered at the above vilocity, and for how long in 10ths or whatever in time would that higher force have to be until the normal acceleration forces of the lift at rest.
Thank you for your time and help.
