An engineer's level with stadia constant of 0.30-m was set up on the line between A and B, the following crosshair readings were observed. If the stadia interval factor of the level is 100, determine the length of line AB. * HAIR READINGS MIDDLE 1.175 ROD FOSITON LOWER 1.020 UFFER 1.330 1.972 A 1.854 1.736 50.20m 51.20m 52.20m 52.21m 53.20m O 54.20m 55.20m

With the line of sight horizontal, solve for the stadia constant given the following? Station Occupied: A Station Observed: B Distance from A to B: [7+7](10) m Stadia Intercept = [10+7](10) em Station Occupied: A Station Observed: C Distance from A to C: [7](10) m Stadia Intercept = [10](10) cm Fundamental of surveying
