Ultimate Strength of the Human Femur – Body Physics ...

Everyday Example: Femur Ultimate Strength. Let's check to see if the measured values for compressive ultimate strength agree with the claim that the human femur can support 30x the adult body weight, or roughly 6,000 lbs . First let's to convert the claimed 6,000 lbs force to Newtons and work in SI units.. An approximate minimum cross-sectional area of the femur is .

Compressive strength - Wikipedia

The compressive strength of the material would correspond to the stress at the red point shown on the curve. In a compression test, there is a linear region where the material follows Hooke's law.Hence, for this region, =, where, this time, E refers to the Young's Modulus for compression.In this region, the material deforms elastically and returns to its original length when the stress is removed.

Compressive Strength of bricks; Generally, bricks have high compressive strength in the range of 5.5 N / mm 2 to 140 N/mm 2. If the crushing strength of the bricks is less than 3.5 N/mm 2 it must not be used. A field test about strength of the bricks is to fall the brick from a height of 1 meter and it must not break in to pieces.
