1. An automatic level with an internal focusing telescope was set up somewhere at mid- length of a long-span steel bridge. The rod readings tabulated below were observed on a stadia rod held successively at the vicinity of the concrete abutments in the southern and northern approaches of the bridge. If the stadia interval factor of the instrument is 98.5, determine the length of the bridge. Rod Hair Readings Position Upper (a) Middle (c) Lower (b) Rod at 2.98 m 1.68 m 0.38 m Southern Approach Rod at Northern 3.54 m 2.02 m 0.49 m Approach

When performing a leveling process for the longitudinal section of a road, the following readings were recorded: The first reading was taken on the leveling number (B.M1), whose Tevel is (60 meters), while the rest of the points were taken on the section points (00+0. 0+50 + 00+ 1... . (While working, lift the device after the fourth, seventh, and tenth reading. Arrange the readings in a table, then complete the table and verify the correctness of the calculations. Draw the segmént and establish a slope line inclined by 0.4% - and its level at the beginning of the project is 60 meters. Find the burial depth in each station.

Hydaway Lake needs to monitor the lake bottom conditions. A contract withEagle Underwater Remote Operated Vehicles (ROV) was established to create a remotelyoperated vehicle. The ROV must be able to determine where it is relative to the sides of thelake. Eagle ROV is using a standard periscope through which a laser measuring system willoperate. The 2.5-m long periscope is attached to the ROV and has an outside diameter of 50mm. The ROV travels at 1 m/sec in water that is 15°C. Based on the assumption that theperiscope is a smooth cylinder determine the moment at the periscope-ROV interface. Thewater is at 15°C.
