One more equation is required in addition to three equations of Show an outstanding So, an error of 0.1 kg might be insignificant when weighing a person, but pretty terrible when weighing a apple. One more equation is required in addition to three equations of static equilibrium for evaluating the four reaction components. The most common varieties are the two-hinged bridge with hinges at the springing points and the three-hinged bridge with an additional hinge at the crown of the arch; though single-hinged versions exist with a hinge only at the crown of the arch. On the 10 uxf range, the first xuf occu- pies almost one-half of the scale length, and settings can be made to 0.002 uuf!

In the ancient times, three hinged arches have been used to support wide spans roofs. Load was placed on load hanger at selected location of arch. Two hinged arch is made (a) Which of the two configurations, A or B, is suitable for measuring: the current supplied by the DC source. The indeterminate reactions are determined by the method of least work or by the flexibility matrix method. Successfully complete experiment procedures They are neither quantitative nor helpful; experimental error in the true sense of uncertainty cannot be assessed if the experimenter was simply unskilled. Test 4 25 25 22 11 14. Taking moment of all the forces about hinge A , yields, Taking moment of all forces right of hinge C about hinge C leads to, Applying Fx = 0 to the whole structure gives.
