What is the basic formula for actual mechanical advantage?
Answers
Answer:
Mechanical Advantage Formula
The efficiency of a machine is equal to the ratio of its output to its input. It is also equal to the ratio of the actual and theoretical MAs. But, it does not mean that low-efficiency machines are of limited use. An automobile jack, for example, have to overcome a great deal of friction and therefore it has low efficiency. But still, it is extremely valuable because small effort can be applied to lift a great weight.
Also, in another way the mechanical advantage is the force generated by a machine to the force applied to it which is applied in assessing the performance of the machine.
The mechanical advantage formula is:
MA = FBFA
Explanation:
MAmechanical advantageFBthe force of the object
FAthe effort to overcome the force

A hydraulic press must be used to press-fit two components together in an assembly process. The system must generate at least 3453 lb. of force to perform the press fit. The piston at the input cylinder is pushed with a force of 723 lbs. and has an area of 33.7 in.2. The output can use up to 15 cylinders that are each 33.7 in.2.
How many output cylinders must be incorporated into the design?
Answers
Note that 5 output cylinders must be incorporated into the design.
Why is this so ?The mechanical advantage of the system is the ratio of the output force to the inputforce. The mechanical advantage of the system is given by
MA = Fout / Fin
where
MA = mechanical advantage
Fout = output force
Fin = input force
MA = 3453/ 723 = 4.77
The area of the output cylinders is 33.7 in.2. The number of output cylinders is given by
n = Aout / Apiston
where
n = number of output cylinders
Aout = area of the output cylinders
Apiston = area of the piston at the input cylinder
hence,
The number of output cylinders must be at least 4.77 / 1 = 4.77. Since the number of output cylinders must be an integer, the number of output cylinders must be 5.

A water turbine is to be designed to produce 27MW when running at 93.7 rev/min
under a head of 16.5m. A model turbine with an output of 37.5kW is tested under
dynamically similar conditions with a head of 4.9m . Calculate the:
a. model speed; b. scale ratio; c. assuming a model efficiency of 88%, estimate the volume
flow rate through the model; and d. if it is estimated that the force on the thrust bearing of
the full-size machine is 7.0GN , determine the bearing thrust of the model.
Answers
The Answers for the given question are as follow:
a. The model speed is approximately 31.62 rev/min.
b. The scale ratio is approximately 0.0417.
c. The estimated volume flow rate through the model is approximately 943.44 m^3/s.
d. The bearing thrust of the model is approximately 9.72 kN.
To calculate the required values for the water turbine model, we can utilize the concept of dynamic similarity.
a. To find the model speed, we can use the principle of geometric similarity, which states that the ratio of speeds is equal to the ratio of the square roots of the head. Thus:
Model speed = (√(Model head))/(√(Full-size head)) * Full-size speed
= (√4.9/√16.5) * 93.7 rev/min
= 31.62 rev/min
b. The scale ratio can be determined using the equation:
Scale ratio = (√(Model power))/(√(Full-size power))
= (√37.5kW)/(√27MW)
≈ 0.0417
c. To estimate the volume flow rate through the model, we can use the power equation:
Model power = (Model efficiency) * (Volume flow rate) * (Model head) * (Gravity)
37.5kW = 0.88 * (Volume flow rate) * 4.9m * (9.81m/s^2)
Solving for the volume flow rate:
Volume flow rate = 37.5kW / (0.88 * 4.9m * 9.81m/s^2)
≈ 943.44 m^3/s
d. To calculate the bearing thrust of the model, we can use the principle of force similarity:
Bearing thrust model = (Model power / Full-size power) * Full-size bearing thrust
= (37.5kW / 27MW) * 7.0GN
≈ 9.72kN

Why is transverse unequal length wishbone preferred to that of equal length?
Answers
Answer:
It allows the wheels to move of the neutral position without the tires scrubbing
Explanation:
The double wishbone suspension is independent and it can be used in both the front wheels and it affords very good control of the outward or inward tilting of the front wheel and it keeps the wheels perpendicular to the road surface
However, when equal length parallel wishbone are installed, it gives rise to scrubbing of the tires as the wheels turn in the tracks
The development of unequal length non-parallel transverse or converging wishbones with A-arms suspension resolved the tire scrubbing effect on the wheels when moving out of the neutral position.

an engineering team has a goal of installing new, more efficient solar panels on the international space station . which equation best describes a cost-benefit analysis the team might perform
Answers
In a cost-benefit analysis, the engineering team aims to evaluate the feasibility and value of installing new, more efficient solar panels on the International Space Station (ISS). They can use the following equation:
Net Benefit = Total Benefits - Total Costs
Identify the Total Benefits: The engineering team assesses the advantages and positive outcomes associated with the new solar panels. These benefits could include increased energy generation, reduced reliance on other power sources, and potential cost savings.Quantify the Total Costs: The team determines the expenses involved in installing the new solar panels, such as research and development costs, manufacturing, transportation, installation, and ongoing maintenance expenses. They also consider any potential risks or drawbacks associated with the project.Calculate Net Benefit: Subtract the Total Costs from the Total Benefits to obtain the Net Benefit. A positive net benefit indicates that the benefits outweigh the costs, suggesting the project is economically viable. Conversely, a negative net benefit may indicate that the costs outweigh the potential benefits, requiring further evaluation or adjustments to the project.By using this cost-benefit analysis equation, the engineering team can make an informed decision about the installation of new, more efficient solar panels on the ISS.
