Given,

Effort force = 120 N

Load force= 1050 N

Mechanical advantage of a pulley is given by the ratio of load force to the effort force.

[tex] M.A=\frac{Load force}{Effort force} [/tex]

[tex] =\frac{1050}{120} [/tex]

[tex] =8.75 [/tex]

Therefore, the mechanical advantage of the given pulley is 8.75.
