Question
Which of the following best describes mechanical advantage?Question 6Answera.The conservation of work and energyb.The non-acceleration of a frame or machinec.The ratio of output force to input forced.The absolute difference between output power and input power
Solution
The best description for mechanical advantage is c. The ratio of output force to input force.
Mechanical advantage is a measure of the force amplification achieved by using a tool, mechanical device or machine system. Essentially, it is the ratio of the output force (the force that the machine exerts) to the input force (the force that is applied to the machine).
