The correct answer is 115 GPa (16.7 × 106 psi) is the minimum permissible radius of the bone.if a circular solid bone with allowable compressive stress of 130 mpa.
A fundamental unit of pressure or tension measurement in the International System of Weights and Measures is the megaPascal (abbreviated MPa). 1 MPa is equal to 1 N/mm2 and 145 psi. Units of measurement lower than 1 psi typically have limited applicability in the oil industry. Million pascals make up one megapascal. The MPa is primarily used to express the pressure ranges and ratings of hydraulic systems because of its bigger value (1 MPa = 10 bar), which makes it useful for higher range pressure measurement.MegaPascal, or MPa, is a metric pressure measurement equivalent to 1,000,000 Pa. A force of 1 Newton produces a pressure of 1 Pa, or Pascal, on a surface area of 1 square meter.
