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

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.
