Answer:
1788.9 MPa
Explanation:
The magnitude of the maximum stress (σ) can be calculated usign the following equation:
<u>Where:</u>
<em>ρ: is the radius of curvature = 2.5x10⁻⁴ mm (0.9843x10⁻⁵ in)</em>
<em>σ₀: is the tensile stress = 100x10⁶ Pa (14500 psi) </em>
<em>2a: is the crack length = 4x10⁻² mm (1.575x10⁻³ in) </em>
Hence, the maximum stress (σ) is:
Therefore, the magnitude of the maximum stress is 1788.9 MPa.

Answer:
Correct option a) True.
Explanation:
It is true since the Vickers hardness value refers to the force applied in a 136 ° diamond tip penetrator divided by the surface of the groove produced in the material, the lower the impression made on this greater the value will be end of the Vickers measurement and greater its hardness.
The equation to determine the Vickers hardness value will be:
Hv= ((1.854 × P)/(d²)) (kg/mm²)
Therefore a value of 220 Vickers refers to a harder material than another value of 180 Vickers.
Penetrating finishes are absorbed by the wood and dry inside the wood. Interior wood stain is used to accentuate the grain in natural woods or plywood while still adding some color. While wood stains offer some level of protection on wood, it's recommended to use stain in combination with a surface finish.
