finite element method
2. Aluminum fins with rectangular profiles (5 mm wide and 1 mm thick) are used to remove heat from a surface whose temperature is 150°C. The temperature of ambient air is 20°C. The thermal conductivity of aluminium is 168 W/m.K. The natural convective coefficient associated with the surrounding air is 35 W/m2.K. The fins are 150 mm long and the heat loss from the tip of the fin may be neglected. (a) Determine the temperature distribution along...

Question#1140Marksl The shaft shown in the figure is rotating at 650 rpm and it receives 5592.75 W through a flexible coupling at its right end. The power is delivered to an adjacent shaft through a single helical gear B having a normal pressure angle of 20° and a helix angle of 15o. The pitch diameter for the gear is 105.1814 mm (4.141 in). A spacer is used to position the gear relative to bearing C. The...

A gear reduction unit uses the countershaft shown in the figure. The solid steel shaft is simply supported by bearings at points O and C. Gear A receives power from another gear with the transmitted force FA applied at the 200 pressure angle as shown. The power is transmitted through the shaft and delivered through gear B through a transmitted force Fa at the pressure angle shown. 0 350 mm 225 ma Gear A 500-mm dia Gear B 200 mm...
