Work done on femur

  1. Nov 8, 2009 #1
    How much work is done by an external force of 151 N when it is applied to a 435 mm femur? Model the bone as a hollow cylinder with inner radius R1 = 4.20 mm and outer radius R2 = 12.60 mm. Young's modulus for the bone is Y = 1.67×1010 Pa.

    Could someone please help me approach this problem?

    Hi as76, welcome to PF.

    (1) How is the force applied (e.g., axial, torsion, shear?)

    (2) Do you know how to calculate work done by an applied force on a deformable object?
