1. What is the combined effect of curvature and refraction for a 300 foot long level shot?
2. A level loop closed -0.09'. There were ten turning points in the loop.
How much (and in what way) should the preliminary elevation of the seventh turning point be adjusted (± 0.01')?
3. An equal tangent vertical parabolic curve has the following characteristics:
PC Station is 23+28.97. PC elevation is 244.88'. L = 5.00 stations, G1 = +4.00% and G2 = -5.70%. Prepare complete stakeout notes (at full stations) for this data. Follow the same format as the example problem in the course notes.
A wood board with a 2in. by 4in. cross section is subjected to a tensile load of 100 lb. Determine the average normal stress and average shear stress developed in the wood fibers that are oriented at 30 degrees with the axis of the board.
Discuss whether shoe A (leather) or shoe B (synthetic) is better for the environment based on the data in the table below. Is it possible to weight one aspect (air
In part (a) of this question we are asked to calculate τmax. In order to do this we separate the cross section at the neutral axis and take the entire upper half (as shown in the cramster solution).
By comparing these relations to Koenig's diagram, come up with the rules to obtain these eight thermodynamic relations from this diagram.
What would be the load carrying capacity of a 250 mm-diameter and 15 m-long timber pile driven into soft clay with an unconfined compressive strength of 40 Kpa? What percentage of the total load is carried by the shaft?
A singly reinforced concrete beam has b=24in, d=12in and it is reinforced with 6#9 bars. If f'c=4ksi and fy=60ksi, determine the beam capacity, Mu = fMn.
A 10 feet thick clay that was unsaturated with a unit weight of 108 pcf and a water content of 20% gets saturated and also swells by 20% due to rain. G=2.70.
Calculate the Euler buckling load for a mild steel rod of length 5m and diameter 25mm when pinned at each end and axially loaded. If this rod is to be used again with an initially straight axis, determine the maximum permissible
A well of 0.1 m radius is part of a well point network to keep an excavation dry (Figure P6.13). The groundwater at the far edge of the excavation must be 0.5 m below the base.
Boxes are placed on a slope at uniform intervals of time trelease and slide down the slope with uniform acceleration. Knowing that as a box B is released, the preceding box A has slid 6 meters down the slope and that 1 second later they are 10 meters..
Determine the amplitude X of the steady-state motion if the viscous damping coeffi- cient c is (a) 0 and (b) 60 lb-sec/ft Compare these amplitudes to the static spring deflection δst.
What are the inputs needed to determine stress a polymer with a fixed end on one side, and the other with a tension force of 50,000 lbs a year after the load is applied?
