The normal force that acts on the cross-section located 3.0 m down from the top is the sum of the pillar''s weight and the sculpture''s weight. Once we have the normal force, we use to find the stress. To find the compressive strain, we find the value of Young''s .

In the linear limit of low stress values, the general relation between stress and strain is. stress = (elastic modulus)×strain. stress = (elastic modulus) × strain. As we can see from dimensional analysis of this relation, the elastic modulus has the same physical unit as stress because strain is dimensionless.

Fundamentals. Allowable Stress (Strength) The allowable stress or allowable strength is the maximum stress (tensile, compressive or bending) that is allowed to be applied on a structural material. The allowable stresses are generally defined by building codes, and for steel, and aluminum is a fraction of their yield stress (strength): In the ...
Since stress is a unit of pressure (usually expressed in MPa, or ) and strain is dimensionless, Young''s modulus is also a unit of pressure. It is typically expressed in GPa, or 1000 MPa. You may also have heard of other elastic constants, such as the shear modulus, bulk modulus,, …
