Mechanical Advantage;The ratio of load and effort is called mechanical advantage of any machine.Mathematical Formula Of Mechanical AdvantageMechanical Advantage = Load / EffortUnit Of Mechanical AdvantageAs mechanical advantage is the ratio of two forces, therefore it has no unit.
it is the ratio of output force to the input force
No, it is a ratio - without units.

Poisson's ratio is 0.3 for metals because the metals begin to get thinner the more they are stretched. It also relates a strain that is tensile to a strain that is compressive.Ê
The physical property defined as the ratio of the change in an electric charge in a system to the corresponding change in its electric potential is capacitance. This property is measured in farads (F) and it quantifies how much charge can be stored per unit voltage.
since k=E/3(1-2n): where k=bulk modulus and n=poision's ratio it can be seen that value of poision's ratio can't be smaller than 0.5 in order to keep k be +ve.hence poision's ratio is 0.5
The ideal mechanical advantage is the ratio of the input force to the output force in a system, while the velocity ratio is the ratio of the velocity of the input force to the velocity of the output force. The relationship between them depends on the type of machine, but in general, a higher ideal mechanical advantage tends to be associated with a lower velocity ratio, and vice versa.

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 ratio of output force to input force.
The Poisson's ratio of rubber is typically around 0.5. This means that when rubber is stretched in one direction, it tends to contract in the perpendicular direction. This property affects the material's mechanical properties by making it highly flexible and able to return to its original shape after being deformed.

The mechanical advantage of a level is the ratio of the output force to the input force.
