What type of bonding makes up ceramic materials?

What type of bonding makes up ceramic materials? The two most common chemical bonds for ceramic materials are covalent and ionic. For metals, the chemical bond is called the metallic bond. The bonding of atoms together is much stronger in covalent and ionic bonding than in metallic. That is why, generally speaking, metals are ductile […]

What is the maximum shear stress theory?

What is the maximum shear stress theory? The Maximum Shear Stress theory states that failure occurs when the maximum shear stress from a combination of principal stresses equals or exceeds the value obtained for the shear stress at yielding in the uniaxial tensile test. Where do you use maximum shear stress theory of failure? Maximum […]

How does the thermal efficiency of an ideal Otto cycle change with the compression ratio of the engine and the specific heat ratio of the working fluid? It […]

What size deck boards should I use?

What size deck boards should I use? Consider All Three Dimensions When Selecting Your Deck Boards Width: Six-inch wide boards are ideal in most cases. Thickness: Radius-edge, 5/4 material (which can measure anywhere from 1 to 1-1/4 in. Length: When possible, buy decking that can run the full length of your deck. Can you use […]

What is the acceleration if velocity is zero?

What is the acceleration if velocity is zero? so if the velocity does not change with time the acceleration is necessarily zero. Since in your example the velocity is constant during the interval that means dv/dt=0 and therefore that a=0 during the interval. Why acceleration is maximum when velocity is zero? Since acceleration is the […]
