SUMMARY

The discussion centers on calculating the maximum compressive stress in a cane subjected to a vertical force of 110N at a radius of 1.15cm. The correct formula for stress is established as F/A, where F is the force and A is the cross-sectional area. The user initially misapplied the formula by confusing stress with pressure, which is defined as Force/Area. The correct calculation involves using the area of the circular cross-section of the cane, calculated as π(0.0115m)^2.

PREREQUISITES
  • Understanding of basic mechanics and stress calculations
  • Familiarity with the concept of force and area in physics
  • Knowledge of geometric formulas for calculating the area of a circle
  • Basic understanding of tensor and scalar quantities in physics
NEXT STEPS
  • Review the calculation of compressive stress using F/A in different scenarios
  • Learn about the differences between stress and pressure in mechanical contexts
  • Explore the implications of tensor properties in material science
  • Study the effects of varying cross-sectional areas on compressive stress
USEFUL FOR

Students and professionals in engineering, physics, and materials science who are involved in stress analysis and mechanical design.

----A man leans down on a cane with a vertical force of 110.00N. The narrowest part of the cane has a radius of 1.15cm. What is the maximum compressive stress in the cane?----

For this problem I thought I needed to calculate stress, which is P/A . Pressure is the Force/Area...so I did 110N / Pi 0.0115^2 . And then I divided that answer to get the stress, but it was wrong. Can anyone help me figure out what I did wrong? Thanks :)

Stress is not P/A, it is F/A.

(Note : Stress is a tensor, whose elements are determined from the components of force and area vectors, while pressure is a scalar.)
 
oh my bad...thanks :)
