For the rectangular bar shown below with dimensions a 1 cm

For the rectangular bar shown below with dimensions a = 1 cm. b = c = .5 cm. A rectangular block of bone is tested in compression until failure as shown below. Find the state of stress then use Mohr\'s circle to determine the principal stresses and maximum shear stresses for an unknown F_x. If sigma_max =150 MPa and tau_max = 50 MPa, determine the maximum force F_x the bone can withstand before fracturing. Which type of failure occurs?

Solution

The value of maximum force Fx is 345Newton .

The failureoccur in the given bar is creep .
