Mechanical and Materials Engineering Homework Solutions

matrix inversion; temperature node distribution

Please show all the work. The matrix inversion method has to be shown in details, the formula used in the class for temperature node distribution was Tm+1,n + Tm-1, n + Tm, n+1 + Tm, n-1 ? 4Tm,n =0 (where ?m? is the X?axis and ?n? is the Y-axis) Please see attachment for problem. Thanks

Radiation

2 questions, including: Consider the 5m x 5m x 5m cubical furnace ... (see attachment) a) the rate of radiation heat transfer between the base and the side surfaces (see attachment for complete list of questions - thanks!)

First Law of Thermodynamics

Two 800-kg cars moving at a velocity of 90 km/h have a head-on collision on a road. Both cars come to a complete rest after the crash. Assuming all the kinetic energy of cars is converted to thermal energy, determine the average temperature rise of the remains of the cars immediately after the crash. Take the average specific he ...continues
