The data in the original post is all I was given. And for the area since young's modulus is stretching or conpressing an object, I assumed I would need to account for the full bone area (not the ends of course) and the area for that would be (pi)r^2h. The shear modulus would be if the bone was...
Young's Modulus
F/A=Y(deltaL/L)
That's the full Young's modulus expression. I'm not sure what to do with it since I'm missing the force and deltaL (change in length). And I'm not sure what area to use since I should be able to find a before b and i need the length of the bone for the area...
Assume that Young's Modulus for bone is 1.50x10^10 N/m^2 and that the bone will fracture if more than 1.50x10^8 N/m^2 is exerted.
(a) What is the maximum force that can be exerted on the femur bone in the leg if it has a minimum effective diameter of 2.60 cm?
(b) If a force of this...
