Max Compressive Stress in Cane: 0.00245 MPa

[uno]

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
