An undivided rural multilane highway segment is to be widened so as to increase its existing lane widths from 9ft to 12ft. Compute the expected average total crash frequency after widening for the following conditions.
Expected average crash frequency before widening = 20 total crashes/yr
AADT on highway segment = 1800 veh/day
Proportion of total crashes constituted by CMF-related crashes = 0.65

A civil engineer used a 30-m tape in measuring an inclined distance. The measured length on the slope was recorded to be 459.20 m long.
A civil engineer used a 30-m tape in measuring an inclined distance. The measured length on the slope was recorded to be 459.20 m long. The difference in elevationbetween the initial and the end point was found to be 1.25 m. The 30-m tape is of standard length at a temperature of 10ºC and a pull of 5 kg. During measurement thetemperature reading was 15ºC and the tape was supported at both ends with an applied pull of 7.5 kg. The cross-sectional area of the tape is 0.065 cm2 and E = 2.0 x106 kg/cm2. The tape weighs 0.075 kg/m and has a linear expansion is 0.0000116 / ºC. Apply corrections for temperature, pull, and sag to determine the correcthorizontal distance considering a gentle slope.

A liquid (ρ = 1000 kg/m3; μ = 2 × 10–2 N ∙ s/m2; v = 2 × 10–5 m2/s) flows tangentially past a flat plate with total length of 4 m (parallel to the flow direction), a velocity of 1 m/s, and a width of 1.5 m. What is the skin friction drag (shear force) on one side of the plate?
