Want this question answered?
the difference between the real mechanical advantage and the speed ratio is -the real mechanical advantage gets affected by friction so the real mechanical advantage gets smaller than the mechanical advantage you calculate. so the real mechanical advantage gets smaller than the speed ratio (because of the friction) and that's why the efficiency never gets 100% efficient (efficiency ; mechanical advantage/ speed ratio x 100(%))
The total mechanical energy of the system remains the same.
a "lubricant" is a friction-reducing substance: a substance, typically oil or grease, applied to a surface to reduce friction between moving parts
Ima is Ideal Mechanical Advantage and Ama is Actual Mechanical Advantage. The difference is that IMA doesn't take into account elasticity or friction and AMA does.
Friction in a machine can reduce the mechanical energy produced by increasing the amount of energy lost as heat. Friction between moving parts causes resistance, which converts some of the mechanical energy into thermal energy. Minimizing friction through lubrication and proper maintenance can help increase the efficiency of a machine and maximize the amount of mechanical energy it produces.
mechanical friction is when two mechanics create friction
Because it lubricates. Instead of metal-on-metal contact, it puts a film of oil between the metal components, so that it's fluid friction, rather than friction between two solids - the latter of which causes excess wear and can actually fuse components together.

A mechanical mixture is a mixture in which the components can be separated by mechanical means. In other words, there is no chemical bonding. The parts keep their own properties and chemical make up.
Ideal Mechanical Advantage ignores friction. Friction is a force that pops up when you move things. Friction in the direction of motion translates to energy -- lost energy. Unless you want to heat up the world.
1) In machines the mechanical parts which rub with each other wear out. 2) Due to friction between the sole of the shoe and the floor the sole wears out. 3) Tyres of vehicles wear out because of friction. 4) Energy is wasted in overcoming the force of friction.
