What force is needed to break a concrete beam containing no aggregate Show your working on the graph?

To determine the force needed to break a concrete beam containing no aggregate, you'd typically refer to the material's tensile strength or compressive strength. Concrete generally has a low tensile strength, often around 10% of its compressive strength, which can range from 20 to 40 MPa for standard concrete. The force (F) can be calculated using the formula ( F = \sigma \times A ), where ( \sigma ) is the tensile or compressive strength and ( A ) is the cross-sectional area of the beam. Without the specific dimensions of the beam, a precise numerical answer cannot be provided, but this approach outlines the methodology for calculating the necessary breaking force.
