SUMMARY

The maximum compressive stress in a cane subjected to a vertical axial force of 98 N and a cross-sectional area of 4.0 cm2 is calculated using the formula Stress = F/A. The correct conversion of 4.0 cm2 to square meters is essential, where 1 cm2 equals 0.0001 m2. Thus, the area converts to 0.0004 m2, leading to a maximum compressive stress of 245,000 Pa or 0.245 MPa, not 0.00245 MPa as initially calculated.

PREREQUISITES
  • Understanding of basic physics concepts, specifically force and area.
  • Knowledge of stress calculations in materials.
  • Familiarity with unit conversions, particularly between square centimeters and square meters.
  • Basic grasp of metric prefixes and their applications in engineering.
NEXT STEPS
  • Review the principles of stress and strain in materials science.
  • Study unit conversion techniques for area and force measurements.
  • Learn about the mechanical properties of materials, focusing on compressive strength.
  • Explore applications of stress calculations in engineering design and analysis.
USEFUL FOR

Engineers, physics students, and anyone involved in materials testing or structural analysis will benefit from this discussion, particularly those focusing on compressive stress calculations in materials like cane.

1. A man leans down on a cane with a vertical axial force of 98 N. The narrowest part of the cane has a cross-sectional area of 4.0 cm2. What is the maximum compressive stress in the cane in MPa



2. Stress = F/A



3. I first changed 4.0cm^2 to .04m^2. I then took 98N/.04m^2 = 2450 Pa which equals .00245 MPa, but the answer is incorrect. Please let me know what I am missing. Thanks.

I first changed 4.0cm^2 to .04m^2.
To convert cm2 to m2, try it this way:

1 cm2 = (1/100m)2=0.0001 m2
