with a tieto support a weight? Stick with foot support(Pratt Inst, model).Two spring balances.Scale pan and weights.Large protractor. Set up the apparatusas shown in Fig. 18, sothat the stick BO is nothorizontal. Add enoughweights at L to stretch thebalance F nearly to its fullscale reading. The… … Fig. 18 34 LABORATORY MANUAL AC, draw a careful diagram of the three forces with theforce OL to some convenient scale. Compare the result ofthis computation with the reading of the balance F. Also by the same diagram, compute the compression onthe stick BO. To test this, attach a second balance at…
