Calculate the support reactions for the given structures.

Question

Three transportation projects have been proposed to increase the safety in and around a residential neighborhood. Each project consists of upgrading existing street signing to highly retroreflective sheeting to increase visibility. The following table shows the initial construction costs, annual operating costs, useful life of the sheeting, and salvage values for each alternative. Annual Operations and Maintenance Initial Construction Alternative Cost ($) 1 16,000 2 3 7,500 18,000 Costs ($) 2,000 3,750 2,000 Useful Life (years) Salvage Value ($) 10 5 10 6,000 850 7,300 Assume that the discount rate is 10 percent. Calculate the present worth (in dollars) for each alternative. (Assume for Alternative 2 that new sheeting must be purchased at the end of the first five years, and that all operations and maintenance costs are due at the end of each year.) PW1 PW 2 = $25967 Your response differs from the correct answer by more than 10%. Double check your calculations. = $21185.5 x PW 3 = $…

Average demand on a rural roadway ranges from zero to 700 veh/day when the cost per trip goes from $1.50 to zero. (a) Calculate the net user benefits per year (in dollars) if the cost decreases from $1.00 to $0.50/trip (assume a linear demand function). Enter a number. (b) Compare the value calculated in (a) with the benefits as calculated in typical highway studies. (Enter the benefits in dollars as calculated in typical highway studies.) $

help me with this Question for revision purpose and as well with references The office building was built in year 2017 and has not obtained any Green Mark certification before. The office building is occupied by a single tenant/entity. The building management team had done an analysis of the building’s energy performance by extracting the data from the various systems. The current performance and findings of the systems are listed in Appendix A. The client is considering to have the building undergo retrofitting to improve the building’s energy performance. The objective is to achieve Green Mark Gold Plus under the new Green Mark 2021 framework. For part (a) below, you are to use Pathway 1: EUI for this. (a) As part of the feasibility exercise, you are to interpret the current performance of the existing building based on the data available (Refer to Appendix A). You should then organise and present to the client how does the current building relate to the Energy Efficiency Section of…
