SUMMARY

The average person can determine the maximum force they can exert when pushing by utilizing a spring-type bathroom scale. This method involves pushing the scale against a wall to measure the force applied. Key factors influencing this measurement include the average weight of the individual and the coefficient of static friction between the surfaces involved. The discussion emphasizes the importance of practical experimentation over theoretical assumptions in understanding real-world applications.

PREREQUISITES
  • Understanding of basic physics principles, particularly force and friction.
  • Familiarity with the concept of static friction and its coefficients.
  • Knowledge of how to use a spring-type bathroom scale for force measurement.
  • Basic grasp of experimental methods in physics.
NEXT STEPS
  • Research the average coefficient of static friction for various surface combinations.
  • Learn about the physics of force and motion, particularly Newton's laws.
  • Explore methods for measuring force using different types of scales.
  • Investigate the impact of body weight on force exertion capabilities.
USEFUL FOR

This discussion is beneficial for physics students, fitness enthusiasts, and anyone interested in understanding human force exertion in practical scenarios.

e.g. pushing a door with x-lbs of resistance, assuming a person is exerting force perpendicular to the door, 36" from hinge. What is that x-lbs (max) an average adult could pushing with ease?

Thanks

This is really a question of two related parameters:

1. How heavy is the average person?

2. What is the average coefficient of static friction (for all combination of surfaces), i.e., what is 'typical'?

When you answer these two, you should be able to extract an answer.
 
Why don't you find a spring-type bathroom scale, hold it up against a wall, and push. What does the scale read? There's your answer (if you are 'average,' whatever that means). :smile:

I like this solution. Sometimes experiment is the way to go. Theory can help you only so much because of all the assumptions that one has to make to approximate any real world situation. =]
