MOTOR TEMPERATURE RATINGS A frequently misunderstood subject related to electric motors is insulation class and temperature ratings. This paper tries to describe‚ in basic terms‚ the temperature relationships that are meaningful in standard AC induction motors. Some of the same information can be applied to DC motors but DC motors are more specialized and some of the ratings are slightly different. Perhaps the best way to start is to define the commonly used terms. MOTOR SURFACE TEMPERATURES

Climate Change Beliefs and Cultural Values Controversy surrounding the public understanding of climate change is influenced by the deficit in cognition of scientific information. As a result the knowledge deficit‚ people turn to cultural differences for alternative explanations. In a straight forward explanation‚ the difference in opinions is a result of both ignorance and culture. This view aligns with Kahan et al.’s cultural cognition thesis‚ according to which the political disagreement about

July 21‚ 2013 Introduction to Scientific Thought: Science Experiment Project Introduction My wife and I love to cook and especially love to make sweet things. Every year around late April or early May‚ we travel past Marble Falls to Sweet Berry Farms and hand pick strawberries to make our favorite sweet treats. My wife is somewhat of an expert in the making of strawberry jam and I dabble in desserts made with chocolate; strawberries dipped in milk‚ dark‚ and white chocolate are my personal favorites

Cheyenne Kenny September 29‚ 2014. Biology Properties Of Water Adhesion How does temperature change affect surface tension? As the temperature of a liquid increases‚ its surface tension decreases. When water heats up‚ the movement of its molecules disrupts the imbalanced forces on the surface of the water and weakens its sheet-like barrier of tightly bound molecules‚ thereby lowering the surface tension. This is why hot water is more effective when cleaning; its low surface

Bread Mold Experiment By: Stephanie Westover PURPOSE The purpose of this experiment will be to determine how temperature affects the growth of mold on wheat bread. The researchers choose this topic because she thinks it will be beneficial to find a way to keep food from molding. Determining how long bread can be stored before molding can help save money‚ prevent illness and preserve freshness. The question the researcher will attempt to answer is how freezing
