A four-lane freeway (two lanes in each direction) is located on rolling terrain and has 12-ft lanes, no lateral obstructions within 6 ft of the pavement edgess, and there are two ramps within three miles upstream of the segment midpoint and three ramps withing three miles downstream of the segment midpoint. The traffic stream consists of cars, buses, and large trucks (no recreational vechicles). A weekday directional peak-hour volume of 1800 vehicles (familar users) is observed, with 700 arriving in the most congested 15 min period. If a level of service no worse than C is desired, determine the maximum number of large trucks and buses that can be present in the peak-hour traffic stream.
a particle moving along a straight path decelerates according to a = -kv. this represent a drag-induced deceleration. assume that the intial velocity is vo at t=0 and s = 0. determine the velocity of the particle both

Calculate the moments M_A and M_B about point A for the forces applied at points A and B. Then, determine the resulting couple moment M_R. Assume that a positive moment produces a counterclockwise rotation whereas a negative moment produces a cloc..
A delivery company accepts only rectangular boxes the sum of whose length and girth (perimeter of a cross section) are equal to 108cm. Find the dimensions of an acceptable box of a largest area.
What are 3 of the equivalent fixed-point problems for f(x) = x2 - x -2=0?
How much of a reduction in the automobile emission rate would be required to achieve the maximum eight-hour average NAAQS for CO at steady state 9ppmv (10.3 mg/m3)?
For the data given below, derive the 2-hr unit hydrograph for a watershed having a drainagearea of 216 km^2, assuming a constant baseflow of 20 m^3/s.
A 2000-ft vertical curve connects a +3% grade to a -5% grade. If the vertical tangents intersect at sta. 52 + 60.55 and elevation 877.62 ft, calculate the elevations at the VPC, VPT, high point, and sta. 54 + 00.
At a section in a beam the tensile stress due to bending is 70 N/mm 2 and there is a shear stress of 25 N/mm 2 . Determine from first principles, the magnitude and direction of the principal stresses and calculate the max shear stress.
Compute the ratio of the nominal flexural strength of the beam to the maximum service load moment, and compare your findings to the ACI load factors and strength reduction factor.
Which software do we use to calculate force and moment, and draw shear and moment diagram? I really need this software to design my structural project. Please helps me... thank you so much
