Can you help me or help me? Could you help me is more polite than the other one. Can you help me isn’t much of a request and more of a surety that the other person won’t deny. ‘Can’ shows power or ability and usage of ‘Could’ shows polite way for seeking permission. How do […]
What are modal parameters?
What are modal parameters? Modal parameters are related to the physical and mechanical properties of the analyzed structure, like mass, stiffness, and energy dissipation, thereby allowing for their characterization even in the absence of viable experimental testing procedures, through the solution of an inverse problem. What are the parameters that are determined in dynamic analysis? […]
Are water soluble vitamins damaged by heat?
Are water soluble vitamins damaged by heat? Some Water-Soluble Vitamins Are Lost in the Cooking Process Some nutrients are easily deactivated or can leach out of food during the cooking process. Water-soluble vitamins, such as vitamin C and the B vitamins, are particularly susceptible to being lost during cooking ( 6 , 7 , 8 […]
What are thermodynamic parameters?
What are thermodynamic parameters? Thermodynamic parameters The central concept of thermodynamics is that of energy, the ability to do work. The most common conjugate thermodynamic variables are pressure-volume (mechanical parameters), temperature-entropy (thermal parameters), and chemical potential-particle number (material parameters). Why is it important to study thermodynamics? Thermodynamics is a very important branch of both physics […]
What are point defects and line defects?
What are point defects and line defects? In a crystalline solid, when the ideal arrangement of solids is distorted around a point/ atom it is called a point defect. Defects or Imperfections in crystalline solid can be divided into four groups namely line defects, point defects, volume defects and surface defects. What are the different […]
How is sidewall height calculated?
How is sidewall height calculated? The sidewall height can be calculated by multiplying the ratio (70 or 0.70) by the width (225): 225 millimeters x 0.70 = 157.5 millimeters. The number 15, or R15, is the diameter of the wheel (or rim) given in inches. What is sidewall height? It’s the height of the sidewall […]
How do you calculate the diametral pitch of a bevel gear?
How do you calculate the diametral pitch of a bevel gear? The Diametral Pitch (DP) is the number of teeth per inch of diameter of the pitch circle. The units of DP are inverse inches (1/in). The Diametral Pitch (DP) is equal to π divided by the Circular Pitch (CP). What is Dedendum formula? Explanation: […]
What are the 4 acceptable thawing methods?
What are the 4 acceptable thawing methods? There are four acceptable methods for thawing food: in a refrigerator, under cold running water, in a microwave, or as part of the cooking process. How is defrosting done? The defrost mechanism in a refrigerator heats the cooling element (evaporator coil) for a short period of time and […]
What is SAE 1020 steel?
What is SAE 1020 steel? AISI 1020 has low hardenability properties and is a low tensile carbon steel with a Brinell hardness of 119 – 235, and a tensile strength of 410-790 MPa. It has high machinability, high strength, high ductility and good weldability. It is normally used in turned and polished or a cold […]
Can two contradictory statements be false?
Can two contradictory statements be false? The textbook definition says contradictory statements can be neither both true nor both false. Given a contradiction, once you prove that one is false, you have already proved that the other is true. Contrary statements, by definition, cannot both be true, while they can be but are not necessarily […]
