Answer:
3
Explanation:
From the question given above, the following data were obtained:
Effort = 5 N
Resistance = 15 N
Mechanical advantage =?
Mechanical advantage is simply defined as the ratio of the resistance to the effort. Mathematically, it can be expressed as:
Mechanical advantage = Resistance /Effort
With the above formula, we can obtain the mechanical advantage as follow:
Effort = 5 N
Resistance = 15 N
Mechanical advantage =?
Mechanical advantage = Resistance /Effort
Mechanical advantage = 15 / 5
Mechanical advantage = 3
