A vertical curve has its highest point at a distance 48 meters from point PT. The curve is having two tangents having a grade of +6% and -4% which intersects at point PI. The curve passes thru point A at station 25+140. The elevation of point Pl is 100 meters above sea level at 25+160 station. Determine: • The height of the Maximum Offset (H) • The Length of the Curve (L) • Elevation of the highest point (hp)

Electronic Spreadsheet

Tabular listing has many advantages ranging from time management to efficient scheduling of tasks. Electronic spreadsheets allow the user to tabulate and analyze data, using its easy-to-use interface. An electronic spreadsheet is a staple application used among accountants, management staff, and IT professionals. It is used in various sectors worldwide for data management. An electronic spreadsheet is a system and computer software that could be used to do numerical computations automatically. Spreadsheet application programs are often organized as a table with rows and columns. Each row and column intersect to form a cell, which may be used to store data. These data can take the form of a written label, a number, or a formula that combines information from other cells.
