In 2019, a single engineer had a gross income of $68,000 and itemized deductions of $13,400. Determine the amount of minimum federal tax he must pay.

In your own words, explain what is meant by OH&S risk and risk assessment.

As an engineer you are responsible to in charge to conduct an experiment for this traffic flow analysis: At 2:00 P.M. a traffic accident closes a road to all traffic. At 2:15 P.M. the road is partially opened with a capacity (car departs) of 1,500 veh/h. Finally, the wreckage is removed, and the road is restored to full capacity (car departs) (3,500 veh/h) at 2:35. From 2:00 to 2:35, car arrives at a constant flow of 2,500 veh/h and then drops to 2,000 veh/h thereafter. Assume D/D/1 queuing to determine

1. Total delay: __________ veh-min

1. Longest vehicle delay under LIFO _________ min

1. Time of queue dissipation: ___________ min

Queue length at 60 min: ___________veh

1. Longest (max) wait of any vehicle (assuming FIFO): ____________min

1. Longest (max) queue length: ____________ veh

1. how a graphical representation of the solution and clearly label the parameters and axis with the appropriate units accordingly.

Design the concrete mix according to the following conditions:

Design Environment
Pavement slab, Bozeman, Montana (cold climate)
Required design strength = 3000 psi

Slab thickness = 12 in

Statistical data indicate a standard deviation of compressive strength of 250 psi is expected (more than 30 samples)

Only air entrainer is allowed.
Available materials
Air entrainer: Manufacture specification is 0.15 fl oz/1% air/100lb cement

Coarse aggregate: 2in. nominal maximum size, crushed stone
Bulk oven dry specific gravity = 2.573, absorption = 2.8%
Oven dry rodded density = 120 pcf
Moisture content = 1%
Fine aggregate: Natural sand
Bulk oven dry specific gravity = 2.540, absorption = 3.4%
Moisture content = 4.5%
Fineness modulus = 2.68

The Modified Puls method is used for reservoir routing while the Muskingum method is used for river routing. Discuss the problems that would occur if one tried to use the Modified Puls method for river routing (i.e. why isn’t the Modified Puls method well suited for river routing?).

22. List two important characteristics of the rock formation/rock mass that may control design bearing pressure considerations and rock mass behavior.

A vertical tangent at 4.7% intersects a tangent at -3.9% at a PVI station of 310+11.23 with an elevation of 903.00 ft. Using a vertical curve of length 493 ft., find the elevation of each full station along the curve. What is the station of the turning point on the curve? {If your calculations result in more than 6 stakes on the curve, evaluate only the first 6}.

What is the section modulus in the stronger axis of a W14X82

A) 92.2

Should laboratory-tested core sample shear strength be factored up, down, or unchanged to develop an allowable rock mass shear strength in design of the foundation system?

List one common method by which rock strengths are tested for the Rock Mass Rating Classification?

An underground mine with large rooms or bays and pillars, with little additional bolting or stabilization required. Boat tours are provided and, normally, available to the public. Given the description, what would you expect the Rock Mass Rating to likely be and why?

For design, the daily car, pickup truck, and light van traffic is 20,000; and the daily truck traffic consists of 200 passes of single-unit trucks with single and tandem axles, and 410 passes of tractor semi-trailer trucks with single, tandem, and triple axles. The axle weights are :cars, pickups, light vans = two 2000-lb single axles;single-unit trucks = 10,000-lb steering, single axle= 22,000-lb drive, tandem axle and: tractor semi-trailer trucks = 12,000-lb steering, single axle,= 18,000-lb drive, tandem axle,= 50,000-lb trailer, triple axle: QUESTION: Using D=10 inches, what is the 18-kip–equivalent single-axle load (18-kip ESAL) for cars, pickups, and light vans,  the 18-kip–equivalent single-axle load (18-kip ESAL) for Single Unit trucks and the 18-kip–equivalent single-axle load (18-kip ESAL) for Tractor Semi-Trailer Trucks?

A 0% grade meets a 3% grade at station 24+00.00 and an elevation of 372.15 ft. For a passing sight distance of 2,000 ft, find the following:

a. Minimum length of the vertical curve that allows for passing using the minimum curve length equations.

b. Calculate the elevation of the middle point of the curve.

c. Calculate the elevation of the road at station 23+00.00.
