Referring to SANS 1575 Burnt clay paving units Modulus of rupture 7.6.11
c) a mechanism capable of applying a force uniformly along the cylinder and of increasing the stress at a rate of 1MPa +- 0.2MPa per second.
What would be the load rate in Newton's per second for a sample 200mm long x 100mm wide x 50mm thick?
1 pascal = 1[N/m²] therefore 1Mpa = 1 000 000 [N/m²] or for ease of calculation 1 MPa = 1000[kN/m²]
