Answer: The mechanical advantage of the hammer is 4.
Step-by-step explanation:
We know that the mechanical advantage of the hammer is is given by the ratio between the force applied on the hammer and the force required to overcome the given force.
Force applied = 40 N
Force required= 160 N
Mechanical advantage =[tex]\frac{\text{force required}}{\text{force applied}}[/tex]
Mechanical advantage =[tex]\frac{160}{40}=4[/tex]
Hence, the mechanical advantage of the hammer is 4.
