A bending moment of 2000 N ⋅ m is applied to a 40-mm-diameter shaft. Estimate the bending stress at the shaft surface. If a hollow shaft of outside diameter 1.15 times inside diameter is used, determine the outside diameter required to give the same outer surface stress.

answer and explanation;

composition refers to both the types of minerals within a rock and the overall chemical makeup of the rock while texture refers to the size and arrangement of the minerals or grains that make up a rock. both composition and texture can be used to classify rocks, such as igneous rocks. texture describes how the rock became solid or crystallized from liquid, melted rock. composition of a rock describes the minerals that make up a particular rock.
