Consider the following scenario: You are working in the automotive sector to develop new brake materials. You want to assess the friction behavior of a new alloy for the pad with a ball-on-flat tribometer (see figure on the right). Knowing that the maximum stress caused during braking is on average 380 MPa and you want to replicate similar stresses during the testing, what should the applied normal load be? You can assume a fully elastic contact.
