484 tons. The sum of these calculated values gives P4Q 2-765 I IS4-4219 tons, a resull which agrees with the sum already calculated, viz. 4-25, within thelimits of accuracy adopted in the calculations. EXPT. 20.—Reactions of a beam. Suspend a wooden bar from twosupports, using spring balances so… … Fig. 11C—Apparatus for determining the reactions of the supports of a beam. Place some loads on the beam and calculate the reactions, neglecting theweight of the beam. Again read the spring balances, P and Q, lb. weightsay. The differences (P - Px) and (Q t Qj) lb. weight should agree with…
