A lever arm is essentlally used to increase the stresses on a specimen. It is often the case when vertical loading cannot achleve the desired stress due to a heavy mass Incapable of being supported by the hanger below. In these cases a simple beam Is attached and an Increased moment is applied. To calculate the new increased stress the lever arm's beam ratio is utilised. Let's assume the following masses on a shear box of 100x100 mm In effective size. Consider the apparatus displayed below and calculate the essential test masses. Consider 50, 100 and 150% stress.
