A metal plate of thickness 200 mm with thermal diffusivity 5.6 x10-6 m²/s and thermal conductivity 20 W/mK is initially at a uniform temperature of 325°C. Suddenly, the 2 sides of the plate are exposed to a coolant at 15°C for which the convection heat transfer coefficient is 100 W/m²K. Determine temperatures at the surface of the plate after 3 min using (a) Lumped system analysis (b) Analytical one term approximation (c) One dimensional Semi infinite solid Analyze and discuss the results
Problem 3 This problem maps back to learning objectives 1-4 & 8. Consider the particle attached to a spring shown below. The particle has a mass m and the spring has a spring constant k. The mass-spring system makes an angle of 0 with respect to the vertical and the distance between point 0 and the particle can be defined as r. The spring is unstretched when r = l. Ꮎ g m a) How many degrees of freedom is this system and what are they? b) Derive the equation(s) of motion that govern the movement of this system.
