Explanation:
Strengthening is the method to improve the strength of material because different type of material property requires for different requirement .Some times requires more ductility,some time requires more strength.
When impurities are mixed with the pure metal then the strength of metal will increases and this is called the strengthening of metal.
The methods of strengthening are as follows
1.Solid solution strengthening and alloying
2.Work hardening
3.Transformation hardening
4.Grain boundary strengthening
5.Precipitation hardening

Answer:
The ideal mechanical advantage (IMA) of the pulley is 6
Explanation:
The question parameters are;
The mass of the actress playing Peter Pan = 125 lb
The force applied by the stagehand to the pulley to hoist her = 30 lbs
The Ideal Mechanical Advantage (IMA) of a pulley = The number of strands (rope) the pulley has
Therefore, the Ideal Mechanical Advantage (IMA) of the given pulley with 6 strands = 6.
