Plates and rods are frequently used to help rehabilitate broken bones. Calculate the shear stress in the lower 5 mm diameter biomedical bolt if it is supporting a 1,200N force from the bone.

The cable of hoist has a cross sectional of 80mm2.The hoist is used to lift a crate weighining 500 kg.The free length of of the cable is 30 m.Assume all deformation is elastic. (a) what is the stress on the cable. (b) How much will the cable extend if it is made from steel(E-200 Gpa)? (c) How much will the cable extend if it is made from polypropylene(E-1.2 Gpa)?

A sample of silicone breast implant, polydimethylsiloxane (PDMS), is placed under unconfined compression. The magnitudes of the resulting longitudinal and transverse strains have been measured to be 2.7 and 1.341, respectively. The young's modulus of the implant is 500 kPa. Calculate the shear and bulk moduli.

The error in a measurement due to strain when using a tape measure depends on the material that it is made of. For a tape with a cross section of 10 mm by 0.7 mm, calculate how much error is introduced in inches into the measurement at a 300 ft length if the tape is pulled with 80 N and if the tape is made of: a) mild steel (E = 30 x 10^6 psi), b) polycrystalline aluminum (E = 10 x 10^6 psi) c) fiberglass composite (E = 3.5 x 10^6 psi in the long direction)
