Question

. An effort of 4 kgf is applied on a machine for movement of a load of 100kgf. Calculate mechanical advantage​

Answer 1

Given :-

Effort applied on the machine = 4 kgf

Load on the machine = 100 kgf

To Find :-

The mechanical advantage.

Analysis :-

Here we are given with the effort and the load.

In order to find the mechanical advantage substitute the given values in the question such that mechanical advantage is equal to load divided by the effort.

Solution :-

Using the formula,

$\underline{\boxed{\sf Mechanical \ advantage=\dfrac{Load}{Effort} }}$

Given that,

Effort = 4 kgf

Load = 100 kgf

Substituting their values,

⇒ m = 100/4

⇒ m = 25

Therefore, the mechanical advantage is 25.

Answer 2

Gɪᴠᴇɴ :

• An effort of 4 kgf is applied on a machine to lift a load.

$:\longmapsto\:\:\bf{Effort\:=\:4\:kgf\:}$

• Weight of the load = 100 kgf

$:\longmapsto\:\:\bf{Load\:=\:100\:kgf\:}$

Tᴏ Fɪɴᴅ :

• Mechanical advantage.

Cᴀʟᴄᴜʟᴀᴛᴏʀ :

Wᴇ ᴋɴᴏᴡ ᴛʜᴀᴛ,

➣ Mechanical advantage is the ratio of load to effort of machine or we can say it is the ratio of output of machine to the input of the machine.

↝ Using mechanical advantage formula,

$\red\bigstar\:\:{\underline{\orange{\boxed{\bf{\green{Mechanical\:advantage\:=\:\dfrac{Load}{Effort}\:}}}}}}$

➛ $\sf{Mechanical\:advantage\:=\:\dfrac{100\:kgf}{4\:kgf}\:}$

➛ $\bf\pink{Mechanical\:advantage\:=\:25\:}$

$\Large\bf\purple{Therefore,}$

The mechanical advantage of the machine is 25.

$\:~~~~~~~~~~~~~\:\Large\bf\underline{Extra\:Flavor\::}$

↝ Machine is a device which multiples the force or multiples the speed or it changes the direction of effort.

↝ There are some terms related to machine like

1. Load
2. Effort
3. Velocity ratio
4. Mechanical advantage
5. Efficiency

↝ Load is the output which is overcome by machine whereas the effort is the input to the machine.
