Explanation Calculate the rate of heat transfer through the plate. Q ˙ cond = k A Δ T L k = ( Q ˙ A ) L T 1 − T 2 (I) Here, change in the temperature of plate is Δ T , the temperature at initial and final is T 1 and T 2 , thermal conductivity of the plate is k , area of a window is A , and length of a window is L . Conclusion: Substitute 0 ° C for T 2 , 100 ° C for T 1 , 500 W / m 2 for Q ˙ / A , and 2 cm for L in Equation (I)

Conduction and Convection

When energy travels from one object to another it is said to have undergone heat transfer. Heat transfer is nothing but the transfer of thermal energy or internal energy from one thing to another, like e.g., when a vessel with water, kept on top of a bur…

An AISI 1018 steel ball with 1.100-in diameter is used as a roller between a flat plate made from 2024 T3 aluminum and a flat table surface made from ASTM No. 30 gray cast iron. Determine the maximum amount of weight that can be stacked on the aluminum plate without exceeding a maximum shear stress of 19.00 kpsi in any of the three pieces. Assume the figure given below, which is based on a typical Poisson's ratio of 0.3, is applicable to estimate the depth at which the maximum shear stress occurs for these materials. 1.0 0.8 Ratio of stress to Pmax 0.4 90 0.6 στ Tmax 0.2 0.5a a 1.5a 2a 2.5a За Distance from contact surface The maximum amount of weight that can be stacked on the aluminum plate is lbf.
