The windscreen washers of an old car don't work (W = 0). This could be for two reasons: the windscreen fluid tank is empty (E = 1) or the tube is has a blockage (B = 1). Being an old car, the light to indicate that the windscreen fluid tank is empty only comes on (L = 1) 75% of the time. It will sometimes comes on even if the tank has some fluid in it, with probability 0.25. Of course the tube could be both blocked and the tank empty. (a) Draw the Bayesian network describing the scenario just described, and express the joint probability in factorised form, defining appropriate variables.

A bimetallic strip is used as a sensor. The strip has a length of 20 μm. The width of the strip is 1μm. It has an upper layer made of steel (E = 210 x 10 9 N/m 2 ) and the lower layer made of aluminum (E = 80 x 10 9 N/m 2 ). Each layer is 0.1 μm thick. Determine the equivalent stiffness of the strip in the axial direction. Note that the strips are perfectly attached.
