In the practice of linear expansion metal rod initially had a length of 600mm at a temperature of 21 ° C. was heated to 100 ° C and a length of 0610 mm therefore dilated, its coefficient of thermal linear expansion is: 12.8 X 10.6 mm / mm oC 10.8 X 10.6 mm / mm ° C-1 14.8 X 10.6 mm / mm ° C-1 16.8 X 10.6 mm / MMOC-1
A metal bar of length 6.33 m and linear expansion coefficient of 2.74x105 /°C has a crack half-way along its length as shown in figure (a). After a 45.0-°C temperature rise, the metal buckles upward, having a height h above its original position as shown in figure (b). Find h Submit AnswerTries 0/14
1. Pendulum clocks are very important for the history of exploration. Accurate time was the best way to determine one's longitude, since the time of sunrise or sunset depends sensitively on your longitude. In this regard, the great enemy of accuracy was thermal expansion of the pendulum used for the chronometer. We are considering a large mass attached at the end of a brass rod. The mass at the end is much greater than the mass of the rod, so we...
summarizr the followung info and write them in your own words and break them into different key points. 6.5 Metering Chamber: 6.5.1 The minimum size of the metering box is governed by the metering area required to obtain a representative test area for the specimen (see 7.2) and for maintenance of reasonable test accuracy. For example, for specimens incorporating air spaces or stud spaces, the metering area shall span an integral number of spaces (see 5.5). The depth of...
