A modulus of rupture test is conducted on an MgO refractory brick with the following data obtained: F = 7*10^4 N L = 175 mm b = 110 mm h = 75 mm If the designer were to reduce the height of the refractory brick to only h=64mm, what would be the new necessary load F to break the refractory? Your answer should be in units of Newtons (N).
