The mechanical advantage of a simple lever is C. the ratio of the length of the effort arm to the length of the load arm
Explanation:
There are two types of mechanical advantage for a machine:
The Ideal Mechanical Advantage (IMA) is the mechanical advantage of the machine if there are no loss of energy due to internal frictions, i.e. if the output work is equal to the input workThe Actual Mechanical Advantage (AMA) is the real mechanical advantage of the machine, taking into account the energy lost due to internal frictional forcesThe IMA of a lever can be calculated starting from the assumption that all the input work is transformed into output work with no loss of energy, therefore:
[tex]W_{in}=W_{out}\\F_{in} d_{in} = F_{out} d_{out}[/tex]
where
[tex]F_{in},F_{out}[/tex] are the effort and load forces, respectively
[tex]d_{in}, d_{out}[/tex] are the effort and load arm, respectively
The mechanical advantage is a measure of the multiplication factor of the force, so we can write:
[tex]IMA=\frac{F_{out}}{F_{in}}=\frac{d_{in}}{d_{out}}[/tex]
Therefore, the correct answer is
C. the ratio of the length of the effort arm to the length of the load arm

Who is part of the design team in construction?
Answer:
An architect and engineers are the design team for construction projects. The team itself can also consist of an architectural company and an engineering firm that hires many architects or engineers.
Explanation:
The design team comprises the professionals needed to design the work and perhaps ensure that the work completed follows the project brief.
Designers are likely in the first place to be members of the customer's consultant team. This is generally supported by: architects.
Technologists of architecture.
Engineers of the system.
Engineers of infrastructure.
Designers of landscape.
The growing complexity of the building design means, however, that additional expertise such as: specialized facilities (e.g., kitchens, operating theatres, ponds, recording studios) is increasingly needed.
Designer of materials (for example, structural systems, doors and windows, vitreous or flooring).
Fittings and specialist equipment.
Equipment for audiovisuals.
Facilities for Information and Communications (ITC).
Facilities for safety and security.
Specialist systems (e.g. handling of baggage).
Lighting specialist.
