Design a simple horizontal curve to connect two roadway tangents that deflect at an angle chosen between 50 and 75 degrees. Assign a station to the curve PI and select a curvature of 6 degrees. Provide the curve data including the
1) incremental and
2) total deflection angles to full stations on the curve and to the point of tangency, the
3) chords to previous stations on the curve and the
4) total chords from the tangent at the point of curve to full stations on the curve.
A field sample of medium sand with median grain size of 0.84 mm will be tested to determine the hydraulic conductivity using a constant-head permeameter. The sample has the length of 30 cm and a diameter of 5 cm.
a store charges 1.25 % interest per month in credit purchases. This is equivalent to: what nominal annual interest rate, effective annual interest rate, and effective monthly interest rate
The velocity along a pathline is given by V (m/s) = s^2 x t^(1/2) where s is in meters and t is in seconds. The radius of curvature is 0.5 m. Evaluate the acceleration along and normal to the path at s = 2m and t = 0.5 seconds.
Determine the force members BC, FC, and FE, and state if the members are in tension or compression.
A driver traveling on a roadway decides to overtake a slow-moving truck traveling at 15 mph. The accelerating characteristic of the car is given by the following: dv/dt= 2.08-0.032v where v is the speed (ft/sec), and t is the time (sec).
For a cement paste with an initial water-cement ratio of 0.5, by mass, calculate the mass and volumetric composition of 1 cm^3 of HCP under both wet and sealed curing conditions.
Over the course of 3days, she added another 6lbs of water and at the end of 3days, there was 67lbs of water remaining. A nearby rain gage recorded 0.4 inches of precipitation over the period.
Compute departures and latitudes, linear misclosure, and relative precision for a five-sided, closed traverse. It is given that the aziumuth of AB is 74 degrees 31 minutes, 17 seconds, A = 105 degrees 13 minutes 14 seconds B = 92
the 100 kg crate is originally at rest on the smooth horizontal surface. If a 200 newton force, acting at an angle of 45 degrees, is applied to the crate for 10 seconds. Determine the final velocity of the crate.
The velocity of a body is given by v(t) = 2t+t3. The body starts from rest at time t = 0 at position s(0) = (2,-10). What are the position and acceleration of the body as functions of time At what time, t, does the body cross the X-axis
An element of aluminium in a form of a rectangular parallel pipe has a length 'a' along the x axis of 5.5 in, a length 'b' on the y axis of 4.5 in. Determine the maximum shear stress in the material,the change in length.
