A one-wheeled cart is used to carry 400N load. If the load is at a distance of 30cm from the wheel and the cart is 1.2 m long, what effort should be applied at the handles to lift the load? What are mechanical advantages, velocity ratio and efficiency? Is the efficiency in practice same as calculated one?​

Answers

Answer 1

The load force to effort force ratio is the mechanical advantage. The distance traveled by the effort divided by the load is known as the velocity ratio. Efficiency is a measure of a system's ability to turn input work into productive output work.

Given

Load = 400N

Distance =30cm

Distance = 1.2m

Required to calculate mechanical advantages, velocity ratio, and efficiency

mechanical advantages = Load / Effort

                                        = 400N / Effort

velocity ratio = Distance moved by effort / Distance moved by the load

                      = 1.2m / 0.3m = 4

Select one valuation technique (Engagement letter, Valuation report, methodologies selection etc...) and discuss how it is being used.

Answers

Explanation:

One valuation technique commonly used in business and financial contexts is the Valuation Report. A Valuation Report is a comprehensive document that provides an in-depth analysis and assessment of the value of an asset, business, or investment opportunity. This report is typically prepared by a qualified valuation professional or an appraisal firm.

The purpose of a Valuation Report is to provide an unbiased and well-documented estimation of the fair market value of the subject asset. It serves as a crucial tool for various stakeholders such as investors, shareholders, buyers, sellers, and financial institutions to make informed decisions regarding the value and potential risks associated with an investment or transaction.

The Valuation Report typically includes the following key elements:

1. Introduction: This section provides an overview of the purpose and scope of the valuation, along with the identification of the subject asset and its relevant characteristics.

2. Valuation Methodology: The report outlines the methodologies and approaches used to determine the value. Common valuation methods include the income approach, market approach, and asset-based approach. The selection of the appropriate method depends on the nature of the asset being valued and the availability of relevant data.

3. Data Analysis: This section involves the collection and analysis of relevant financial and non-financial information. It may include financial statements, industry benchmarks, market trends, comparable transactions, and other relevant data.

4. Assumptions and Limiting Conditions: The report explicitly states the assumptions made during the valuation process and any limiting conditions that may affect the accuracy or reliability of the valuation.

5. Valuation Results and Conclusion: The report presents the calculated value of the asset based on the chosen valuation methodology. It may also include a range of values or alternative scenarios if appropriate. The conclusion provides an overall assessment of the value and may include additional insights or recommendations.

A Valuation Report is a valuable tool in various scenarios such as mergers and acquisitions, financial reporting, litigation support, tax planning, and dispute resolution. It provides a detailed analysis that helps stakeholders understand the value drivers, potential risks, and the underlying factors impacting the value of the subject asset.

It is important to note that the preparation of a Valuation Report requires expertise in valuation techniques, financial analysis, and knowledge of relevant industry and market trends. It is often performed by professionals such as Certified Public Accountants (CPAs), Chartered Financial Analysts (CFAs), or Accredited Senior Appraisers (ASAs), who adhere to professional standards and guidelines to ensure the accuracy and credibility of the valuation analysis.
