Required information
The leg bone (femur) breaks under a compressive force of about 6.50 × 104 N for a human and 12.3 × 104 N for a horse.
The human femur has a compressive strength of 160 MPa, whereas the horse femur has a compressive strength of 140
MPa.
What is the effective cross-sectional area of the femur in a horse? (Note: Since the center of the femur contains bone marrow, which
has essentially no compressive strength, the effective cross-sectional area is about 80% of the total cross-sectional area.)

The bimetallic Pt-Ni nanoparticles are expected to decorate on the side surfaces of the aligned TiO2 nanorod arrays. These aligned TiO2 nanoarrays grew on the flat SiO2 monolith. Let's assume that the sizes of the Pt-Ni nanoparticles are > 10 nm. We further assume that you have access to a modern SEM that can produce a probe size as small as 1 nm with a current as high as 1 nA. You are not expected to damage/destroy the sample.
