SUMMARY

The discussion centers on calculating the PSI required to lift a person with a mass of 63.5 kg at an acceleration of 1 m/s². The user applied Newton's second law (F=ma) to determine the total acceleration, combining gravitational acceleration (9.8 m/s²) with the desired acceleration, resulting in 10.8 m/s². The calculated force needed is 685.8 N, which converts to 154.17 lb. With an area of 1.953 in², the required PSI is determined to be 78.9 psi. The calculations are confirmed to be correct, and the user seeks further clarification on the application of this PSI value.

PREREQUISITES
  • Understanding of Newton's second law (F=ma)
  • Basic knowledge of unit conversions (N to lb)
  • Familiarity with pressure calculations (psi)
  • Concept of gravitational acceleration (9.8 m/s²)
NEXT STEPS
  • Research real-world applications of PSI in lifting mechanisms
  • Explore advanced physics concepts related to force and acceleration
  • Learn about hydraulic systems and their pressure requirements
  • Investigate safety factors in lifting calculations
USEFUL FOR

This discussion is beneficial for physics students, engineers, and hobbyists interested in mechanics, particularly those exploring lifting systems and pressure calculations.

I am trying to find the psi needed to lift me off the ground at an acceleration of 1m/s/s so i started with the equation f=ma. For acceleration I added f=m(1m/s/s) but i need to cancel gravity out, so I took 9.8m/s/s + 1m/s/s = 10.8m/s/s. I thought it would work because 1m/s/s was the acceleration I wanted to go. For mass I added my mass in kg. I finally had F=63.5(10.8). I found 685.8n was the force needed. I converted 685.8n to 154.17flb. The area I need the force to be on is 1.953in2. To find the psi, I did 154.17 / 1.953 = 78.9 psi. I am not sure this is right. I am a thirteen year old boy in 7th grade. Any guidance would be wonderful.

The concept is right, and the numbers can be checked by a computer.
 
Psi of what though? Is there a real-world project you are hoping to do?
