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 […]

What is the formula Nplan 33000 is equal to the?
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?
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? 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 is the difference between the fin effectiveness and the fin efficiency?
What is the difference between the fin effectiveness and the fin efficiency? Therefore, the fin effectiveness can be determined easily when the fin efficiency is known, or vice versa. The thermal conductivity k of the fin material should be as high as possible. The overall effectiveness is a better measure of the performance of a […]
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 […]
How do you measure air velocity with a Pitot tube?
How do you measure air velocity with a Pitot tube? The Pitot tube is inserted into the duct with the tip pointed toward the airflow. The positive port of the manometer is connected to the total pressure port (Pt) and the negative to the static pressure port (Ps). The manometer will then display velocity pressure […]
