Question

Q1. Explain the term Mechanical Advantage of a machine.

Q2. What is a lever?

Q3. What did you mean by the mechanical advantage of a lever?

pls give me the answer
plsssssssssssssssssssss​

Answer 1

Answer:

1.Mechanical advantage is a measure of the force amplification achieved by using a tool, mechanical device or machine system. The device preserves the input power and simply trades off forces against movement to obtain a desired amplification in the output force. The model for this is the law of the lever.....

2.a rigid bar resting on a pivot, used to move a heavy or firmly fixed load with one end when pressure is applied to the other.....

please mark as brainliest ...

Answer 2

Answer:

Mechanical advantage is a measure of the force amplification achieved by using a tool, mechanical device or machine system. The device preserves the input power and simply trades off forces against movement to obtain a desired amplification in the output force.

Q2 a handle that you pull or push in order to make a machine, etc. work

Q3 The mechanical advantage of the lever is the ratio of output force to input force, This relationship shows that the mechanical advantage can be computed from ratio of the distances from the fulcrum to where the input and output forces are applied to the lever, assuming no losses due to friction, flexibility or wear.
