The assembly consists of a brass shell (1) fully bonded to a ceramic core (2). The brass shell [E = 96 GPa, 17.4 × 10−6/°C] has an outside diameter of 53 mm and an inside diameter of 33 mm. The ceramic core [E = 260 GPa, 3.5 × 10−6/°C] has a diameter of 33 mm. At a temperature of 14°C, the assembly is unstressed. Assume L = 300 mm. Determine the largest temperature increase that is acceptable for the assembly if the normal stress in the longitudinal direction of the brass shell must not exceed 71 MPa.

Isobars are lines of constant or equal pressure on a weather map. they can be used to find areas of low or high pressure over a broad area, and they can tell us how intense the system may be. on weather maps, you may have noticed areas that have a large l or h over a region with lines circling around them. the l stands for low pressure and h stands for high pressure. the lines circling them are isobars. check out the pressure system and isobars over georgia and florida. what is the present weather in this area ? a) clear and sunny b) cold and cloudy c) changing weather d) lots of precipitation
