Task2:
Noise and Air pollution Caused during Highway Construction and their mitigation measure

Noise Pollution

At the time of highway construction heavy loaded vehicle with material moved so these vehicle create a noise and air pollution due to suspension dust in to the atmosphere .

Fluctuation in traffic is considered as a significant environmental predictor for physical inactivity. The unfit vehicles, engines, cylinders, and horns create the noise and air pollution. Traffic noise pollution along with faulty design and construction of buildings near by roads create physical and mental disturbance and other problems for residents. The traffic noise annoyance is related to lower physical activity.

Mitigation Measure for Noise pollution

We can Reduce Noise pollution by turning off appliances when not in use, use of earplugs, lowering the volume, planting more trees, regular maintenance of vehicles and machines etc. By controlling noise we can control negative health effects that noise pollution has on everyone.

Air pollution

The traffic congestion caused by construction activities and the materials and equipment used in construction may aggravate the air quality problem in non-attainment areas.

Concentrations of air pollutants and adverse respiratory health effects are greater near the road than at some distance away from the road. Road dust kicked up by vehicles may trigger allergic reactions. Carbon dioxide is non-toxic to humans but is a major greenhouse gas and motor vehicle emissions are an important contributor to the growth of CO2 concentrations in the atmosphere and therefore to global warming.

Mitigation measure for air pollution

Construction areas should be enclosed, wherever possible. Green belt along the ROW goes a long way to reduce air/noise pollution effects.

Continuous maintenance of construction site and upkeep of highway will maintain traffic flow and will help to reduce air pollution effects.

Q2. A sphere of radius r and weight W is released with no initial velocity on a (C*) degrees incline and rolls without slipping. Determine: (a) the minimum value of the coefficient of static friction (µ) compatible with the rolling motion, (b) the velocity (Vb) of the center G of the sphere after the sphere has rolled (D*) meters, (c) the velocity (Vc) of G if the sphere were to move (D*) meters down a frictionless (C*) degrees incline. (g = 9.81m/s2) Report the following in the results summary table: part (a): µ = ? (10 points) part (b) Vb = ? (m/s) (10 points) part (c) Vc =? (m/s) (10 points)

You have recently graduated and have been employed by a company proposing a cable car from Hobart city to the top of kunanyi / Mt Wellington. The company is developing a strategy to ensure it achieves ‘best practice’ environmental outcomes.

You have been asked to prepare recommendations for spatial data collection, data management and analysis that will contribute to the whole of the project (from the proposal stage to the completed construction).

List and describe at least four examples of spatial data and spatial technologies that you would recommend to the company and that would support its proposal, including its commitment to achieving best-practice environmental outcomes. Justify your recommendations.

Consider a simply supported beam of length L. The beam experiences a parabolically varying distributed load that varies from 0 at the left support, to a maximum w at midspan, and back to 0 at the right support. The beam has stiffness properties EI. Give a mathematical equation that gives the value of the distributed load intensity at any distance z along the beam in terms of w, L and z. Draw the SFD and BMD of the beam, giving the maximum values in terms of w and L. What is the midspan deflection of the beam in terms of EI and w and L.

2. its a question from transportation

Derive a relation between velocity in rad ial direction v(r) and centerline velocity vc for a fully developed laminar flow inside a horizontal pipe with a head loss h1 for a pipe length L.

A trapezoidal channel is to be designed through a silty clay alluvium on a slope of 0.0035 ft/ft. The angle of repose of the material is 35° and the Manning coefficient is 0.025. If the channel is to be designed to carry a maximum discharge of 700 cfs at a depth of 4.9 ft, determine if rip-rap will be required, and, if so, compute the stone size for both the bed and sides.
