Semi-infinite solids A (initially at 0°C) and B (initially at 100°C) are placed in contact with each other. Materials A and B have identical properties except for conductivity. The conductivities are related by the equation KA = 10kg. Calculate the equilibrium temperature at the surface where the solids come into contact [°C].

A piston engine in which the bore and stroke are of equal dimension is referred to as a "square engine". An 8-cylinder square engine has a displacement of 305 in3. What is the bore and stroke? Round to the nearest thousandth of an inch. "bore" is the diameter of a cylinder, and "stroke" is the height of a cylinder (the distance the piston travels in one stroke). You will need the formula for the volume of a cylinder to solve this problem.

Draw a circular hole of 2cm deep and give dimensions to it.
