1. Platform Balance. The construction of the trip scale is shown in Figs. 1 and 2on this and the following page. This convenient instrumentfor weighing is too often misused in the physical laboratoryand poor results obtained with it. With the observance, how-ever, of a few simple precautions,… … Fig. 2. Sectional View of Balance. platform and note whether or not the pointer swings freelyand equally on each side of the center line of the scale. Thepointer should oscillate at least two divisions to the right andto the left. In too short swings the friction in the bearings makes the scale…
