A circular specimen of MgO is loaded using a three-point bending mode. Compute the minimum possible radius of the specimen without fracture, given that the applied load is 500 N (112 lbf), the flexural strength is 105 MPa (15,000 psi), and the separation between load points is 50.0 mm (1.97 in.).

The value of  minimum possible radius of the specimen without fracture

= 4.23 mm

Explanation:

Given data

Applied load F =  500 N

Flexural strength = 105 M Pa

Separation between load points =  50 mm

The minimum possible radius of the specimen without fracture is given by

= 4.23 mm

This is the value of  minimum possible radius of the specimen without fracture.
