Types of Strength
There are several types of strength that are commonly studied:
Tensile Strength: This is the resistance of a force-motion-and-energy?dictionary=material&did=1131" onclick="getAsistant(this,event,1131,'material');return false;" style="color:#009000;">material to breaking under force-motion-and-energy?dictionary=tension&did=1545" onclick="getAsistant(this,event,1545,'tension');return false;" style="color:#009000;">tension. It is a measure of the maximum amount of tensile stress that a force-motion-and-energy?dictionary=material&did=1131" onclick="getAsistant(this,event,1131,'material');return false;" style="color:#009000;">material can withstand before failure.
Compressive Strength: This is the ability of a force-motion-and-energy?dictionary=material&did=1131" onclick="getAsistant(this,event,1131,'material');return false;" style="color:#009000;">material to withstand force-motion-and-energy?dictionary=forces&did=1087" onclick="getAsistant(this,event,1087,'force');return false;" style="color:#009000;">forces that compress it. It is important in structural force-motion-and-energy?dictionary=design&did=1346" onclick="getAsistant(this,event,1346,'design');return false;" style="color:#009000;">design and force-motion-and-energy?dictionary=materials&did=1131" onclick="getAsistant(this,event,1131,'material');return false;" style="color:#009000;">materials used in force-motion-and-energy?dictionary=construction&did=1766" onclick="getAsistant(this,event,1766,'construction');return false;" style="color:#009000;">construction.
Shear Strength: Shear strength is the maximum resistance of a force-motion-and-energy?dictionary=material&did=1131" onclick="getAsistant(this,event,1131,'material');return false;" style="color:#009000;">material to sliding failure under shear stress. It is crucial in the force-motion-and-energy?dictionary=design&did=1346" onclick="getAsistant(this,event,1346,'design');return false;" style="color:#009000;">design of force-motion-and-energy?dictionary=materials&did=1131" onclick="getAsistant(this,event,1131,'material');return false;" style="color:#009000;">materials used in applications where there is a risk of shearing force-motion-and-energy?dictionary=forces&did=1087" onclick="getAsistant(this,event,1087,'force');return false;" style="color:#009000;">forces.
Flexural Strength: Flexural strength, also known as bending strength, is the force-motion-and-energy?dictionary=material%27s&did=1131" onclick="getAsistant(this,event,1131,'material');return false;" style="color:#009000;">material's ability to resist deformation under load. It is important in the force-motion-and-energy?dictionary=design&did=1346" onclick="getAsistant(this,event,1346,'design');return false;" style="color:#009000;">design of beams, panels, and other structural elements that are subjected to bending force-motion-and-energy?dictionary=forces&did=1087" onclick="getAsistant(this,event,1087,'force');return false;" style="color:#009000;">forces.
